(“Horizon” or the “Company”) and its wholly-owned subsidiaries, including Horizon Bank (“Horizon Bank” or the “Bank”). Horizon Bank (formerly known as “Horizon Bank, N.A.”) was a national association until its conversion to an Indiana commercial bank effective June 23, 2017. All inter-company balances and transactions have been eliminated. The results of operations for the periods ended June 30, 2019 and June 30, 2018 are not necessarily indicative of the operating results for the full year of 2019 or 2018. The accompanying unaudited condensed consolidated financial statements reflect all adjustments that are, in the opinion of Horizon’s management, necessary to fairly present the financial position, results of operations and cash flows of Horizon for the periods presented. Those adjustments consist only of normal recurring adjustments. Certain information and note disclosures normally included in Horizon’s annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in Horizon’s Annual Report on Form 10-K On May 15, 2018, the Board of Directors of the Company approved a three-for-two no three-for-two three-for-two Basic earnings per share is computed by dividing net income available to common shareholders (net income less dividend requirements for preferred stock and accretion of preferred stock discount) by the weighted-average number of common shares outstanding.

Business Combinations [Abstract]
Acquisitions	Note 2 – Acquisitions Salin Bancshares, Inc. On March 26, 2019, Horizon completed the acquisition of Salin Bancshares, Inc. (“Salin”), an Indiana corporation, and Horizon Bank’s acquisition of Salin Bank and Trust Company (“Salin Bank”), an Indiana commercial bank and wholly-owned subsidiary of Salin, through mergers effective March 26, 2019. Under the terms of the Merger Agreement, shareholders of Salin received 23,907.5 87,417.17 $126.7 million. The Company incurred approximately $5.6 million in costs related to the acquisition. These expenses are classified in the non-interest expense section of the income statement and are primarily located in the data processing, professional fees, outside services and consultants and other expense line items. As a result of the acquisition, the Company was able to increase its deposit base and reduce transaction costs. The Company also expects to reduce costs through economies of scale. Under the acquisition method of accounting, the total purchase price is allocated to net tangible and intangible assets based on their current estimated fair values on the date of the acquisition. Based on preliminary valuations of the fair value of tangible and intangible assets acquired and liabilities assumed, which are based on estimates and assumptions that are subject to change, the preliminary purchase price for the Salin acquisition is detailed in the following table. Final estimates of fair value on the date of acquisition have not been received yet. Prior to the end of the one-year measurement period for finalizing the purchase price allocation, if information becomes available which would indicate adjustments are required to the purchase price allocation, such adjustments will be included in the purchase price allocation prospectively. As a result of updated draft valuation estimates, acquired investment securities decreased approximately $387,000, total loans decreased approximately $2.9 million, premises and equipment decreased approximately $4.2 million, goodwill increased approximately $5.4 million, core deposit intangible decreased approximately $1.3 million, other assets increased approximately $4.0 million, total deposits decreased approximately $117,000 and subordinated debentures increased approximately $816,000 compared to previously reported amounts.

Additionally, $ million has been allocated to goodwill and none of the purchase price is deductible. The core deposit intangible is being amortized over years on a straight line basis. The Company acquired various loans in the acquisition that had evidence of deterioration of credit quality since origination and it was probable, at acquisition, that all contractually required payments would not be collected. Loans purchased with evidence of credit deterioration since origination and for which it is probable that all contractually required payments will not be collected are considered to be credit impaired. Evidence of credit quality deterioration as of the purchase date may include information such as past-due non-accrual loan-to-value 310-30) The following table details an estimate of the acquired loans that are accounted for in accordance with ASC 310-30 Contractually required principal and interest at acquisition $ 22,672 Contractual cash flows not expected to be collected (nonaccretable differences) 6,694 Expected cash flows at acquisition 15,978 Interest component of expected cash flows (accretable discount) 735 Fair value of acquired loans accounted for under ASC 310-30 $ 15,243 Estimates of certain loans, those for which specific credit-related deterioration since origination, are recorded at fair value, reflecting the present value of the amounts expected to be collected.

While these securities are held in the available for sale portfolio and held-to-maturity, Should the impairment of any of these securities become other than temporary, the cost basis of the investment will be reduced and the resulting loss recognized in net income in the period the other-than-temporary impairment is identified. At June 30, 2019, no individual investment security had an unrealized loss that was determined to be other-than-temporary. The unrealized losses on the Company’s investments in securities of state and municipal governmental agencies, U.S. Treasury and federal agencies, federal agency collateralized mortgage obligations, and federal agency mortgage-backed pools were caused by interest rate volatility and not a decline in credit quality. The contractual terms of those investments do not permit the issuer to settle the securities at a price less than the amortized cost basis of the investments. The Company expects to recover the amortized cost basis over the term of the securities. Because the Company does not intend to sell the investments and it is not likely that the Company will be required to sell the investments before recovery of their amortized cost basis, which may be at maturity, the Company did not consider those investments to be other-than-temporarily impaired at June 30, 2019. The amortized cost and fair value of securities available for sale and held to maturity at June 30, 2019 and December 31, 2018, by contractual maturity, are shown below. Expected maturities will differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties.

The cash flows of borrowers, however, may not be as expected, and the collateral securing these loans may fluctuate in value. Most commercial loans are secured by the assets being financed or other business assets, such as accounts receivable or inventory, and may incorporate a personal guarantee; however, some short-term loans may be made on an unsecured basis. In the case of loans secured by accounts receivable, the availability of funds for the repayment of these loans may be substantially dependent on the ability of the borrower to collect amounts due from its customers. Commercial real estate loans are viewed primarily as cash flow loans and, secondarily, as loans secured by real estate. Commercial real estate lending typically involves larger loan principal amounts and the repayment of these loans is generally dependent on the successful operation of the property securing the loan or the business conducted on the property securing the loan. Commercial real estate loans may be more adversely affected by conditions in the real estate markets, the general economy, or fluctuations in interest rates. The properties securing the Company’s commercial real estate portfolio are diverse in terms of property type, and are monitored for concentrations of credit. Management monitors and evaluates commercial real estate loans based on collateral, cash flow, and risk grade criteria. As a general rule, the Company avoids financing single purpose projects unless other underwriting factors are present to help mitigate risk. In addition, management tracks the level of owner-occupied commercial real estate loans versus non-owner Real Estate and Consumer With respect to residential loans that are secured by 1-4 loan-to-value 1-4 Mortgage Warehousing Horizon’s mortgage warehouse lending has specific mortgage companies as customers of Horizon Bank. Individual mortgage loans originated by these mortgage companies are funded as a secured borrowing with a pledge of collateral under Horizon’s agreement with the mortgage company. Each mortgage loan funded by Horizon undergoes an underwriting review by Horizon to the end investor guidelines and is assigned to Horizon until the loan is sold to the secondary market by the mortgage company. In addition, Horizon takes possession of each original note and forwards such note to the end investor once the mortgage company has sold the loan. At the time a loan is transferred to the secondary market, the mortgage company reacquires the loan under its option within the agreement. Due to the reacquire feature contained in the agreement, the transaction does not qualify as a sale and therefore is accounted for as a secured borrowing with a pledge of collateral pursuant to the agreement with the mortgage company. When the individual loan is sold to the end investor by the mortgage company, the proceeds from the sale of the loan are received by Horizon and used to pay off the loan balance with Horizon along with any accrued interest and any related fees. The remaining balance from the sale is forwarded to the mortgage company. These individual loans typically are sold by the mortgage company within 30 days and are seldom held more than 90 days. Interest income is accrued during this period and collected at the time each loan is sold. Fee income for each loan sold is collected when the loan is sold, and no costs are deferred due to the term between each loan funding and related payoff, which is typically less than 30 days. Based on the agreements with each mortgage company, at any time a mortgage company can reacquire from Horizon its outstanding loan balance on an individual mortgage and regain possession of the original note. Horizon also has the option to request that the mortgage company reacquire an individual mortgage. Should this occur, Horizon would return the original note and reassign the assignment of the mortgage to the mortgage company. Also, in the event that the end investor would not be able to honor the purchase commitment and the mortgage company would not be able to reacquire its loan on an individual mortgage, Horizon would be able to exercise its rights under the agreement.

In recognition of this, it is management’s policy to convert the loan from an “earning asset” to a non-accruing non-accrual non-accrual non-accrual Non-accrual non-accrual A loan becomes impaired when, based on current information, it is probable that a creditor will be unable to collect all amounts due according to the contractual terms of the loan agreement. When a loan is classified as impaired, the degree of impairment must be recognized by estimating future cash flows from the debtor. The present value of these cash flows is computed at a discount rate based on the interest rate contained in the loan agreement. However, if a particular loan has a determinable market value for its collateral, the creditor may use that value. Also, if the loan is secured and considered collateral dependent, the creditor may use the fair value of the collateral. Interest income on loans individually classified as impaired is recognized on a cash basis after all past due and current principal payments have been made. Smaller-balance, homogeneous loans are evaluated for impairment in total. Such loans include residential first mortgage loans secured by 1–4 family residences, residential construction loans, automobile, home equity, second mortgage loans and mortgage warehouse loans. Commercial loans and mortgage loans secured by other properties are evaluated individually for impairment. When analysis of borrower operating results and financial condition indicate that underlying cash flows of a borrower’s business are not adequate to meet its debt service requirements, the loan is evaluated for impairment. Often this is associated with a delay or shortfall in payments of 30 days or more. Loans are generally moved to non-accrual Loans for which it is probable that the Company will not collect all principal and interest due according to contractual terms, including TDRs, are measured for impairment. Allowable methods for determining the amount of impairment include the three methods described above. The Company’s TDRs are considered impaired loans and included in the allowance methodology using the guidance for impaired loans. At June 30, 2019, the type of concessions the Company has made on restructured loans has been temporary rate reductions and/or reductions in monthly payments and there have been no restructured loans with modified recorded balances. Any modification to a loan that is a concession and is not in the normal course of lending is considered a restructured loan. A restructured loan is returned to accruing status after six consecutive payments but is still reported as TDR unless the loan bears interest at a market rate. As of June 30, 2019, the Company had $3.8 million in TDRs and $2.2 million were performing according to the restructured terms and no The following table presents commercial loans individually evaluated for impairment by class of loan: June 30, 2019 Three Months Ended Six Months Ended Unpaid Recorded Allowance for Average Cash/Accrual Average Cash/Accrual With no recorded allowance Commercial Owner occupied real estate $ 3,851 $ 3,851 $ — $ 5,987 $ 76 $ 6,005 $ 130 Non-owner 1,116 1,143 — 1,260 33 1,293 64 Residential spec homes — — — — — — — Development & spec land 140 139 — 226 2 224 2 Commercial and industrial 1,797 1,778 — 2,073 15 2,078 22 Total commercial 6,904 6,911 — 9,546 126 9,600 218 With an allowance recorded Commercial Owner occupied real estate 371 371 3 372 10 365 10 Non-owner 135 135 40 135 — 135 — Residential spec homes — — — — — — — Development & spec land — — — — — — — Commercial and industrial 1,224 1,224 744 1,252 25 1,258 25 Total commercial 1,730 1,730 787 1,759 35 1,758 35 Total $ 8,634 $ 8,641 $ 787 $ 11,305 $ 161 $ 11,358 $ 253 June 30, 2018 Three Months Ended Six Months Ended Unpaid Recorded Allowance for Average Cash/Accrual Average Cash/Accrual With no recorded allowance Commercial Owner occupied real estate $ 4,765 $ 4,762 $ — $ 5,271 $ 59 $ 5,303 $ 96 Non-owner 1,344 1,360 — 1,591 5 1,559 10 Residential spec homes — — — — — — — Development & spec land 72 70 — 71 — 73 — Commercial and industrial 1,943 1,943 — 1,916 7 1,886 7 Total commercial 8,124 8,135 — 8,849 71 8,821 113 With an allowance recorded Commercial Owner occupied real estate 864 864 184 871 — 885 — Non-owner — — — — — — — Residential spec homes — — — — — — — Development & spec land — — — — — — — Commercial and industrial — — — — — — — Total commercial 864 864 184 871 — 885 — Total $ 8,988 $ 8,999 $ 184 $ 9,720 $ 71 $ 9,706 $ 113 The following table presents the payment status by class of loan: June 30, 2019 Current 30-59 60-89 90 Days or Non-accrual Total Past Due Non-accrual Total Commercial Owner occupied real estate $ 705,186 $ 265 $ — $ 63 $ 4,083 $ 4,411 $ 709,597 Non-owner 781,012 829 — — 1,251 2,080 783,092 Residential spec homes 14,862 — — — — — 14,862 Development & spec land 40,509 453 — — 140 593 41,102 Commercial and industrial 513,126 2,234 499 — 3,021 5,754 518,880 Total commercial 2,054,695 3,781 499 63 8,495 12,838 2,067,533 Real estate Residential mortgage 791,704 2,272 125 77 4,635 7,109 798,813 Residential construction 22,403 — — — — — 22,403 Mortgage warehouse 133,428 — — — — — 133,428 Total real estate 947,535 2,272 125 77 4,635 7,109 954,644 Consumer Direct installment 46,203 180 49 — 36 265 46,468 Indirect installment 326,970 1,268 250 156 1,129 2,803 329,773 Home equity 272,047 640 569 95 2,045 3,349 275,396 Total consumer 645,220 2,088 868 251 3,210 6,417 651,637 Total $ 3,647,450 $ 8,141 $ 1,492 $ 391 $ 16,340 $ 26,364 $ 3,673,814 Percentage of total loans 99.28 % 0.22 % 0.04 % 0.01 % 0.44 % 0.72 % 100.00 % December 31, 2018 Current 30-59 60-89 90 Days or Non-accrual Total Past Due Non-accrual Total Commercial Owner occupied real estate $ 556,516 $ 537 $ 997 $ — $ 3,413 $ 4,947 $ 561,463 Non-owner 716,574 175 19 — 1,046 1,240 717,814 Residential spec homes 4,707 492 — — — 492 5,199 Development & spec land 46,479 — — — 68 68 46,547 Commercial and industrial 390,828 515 736 208 2,059 3,518 394,346 Total commercial 1,715,104 1,719 1,752 208 6,586 10,265 1,725,369 Real estate Residential mortgage 641,500 1,131 56 180 3,269 4,636 646,136 Residential construction 24,030 — — — — — 24,030 Mortgage warehouse 74,120 — — — — — 74,120 Total real estate 739,650 1,131 56 180 3,269 4,636 744,286 Consumer Direct installment 38,027 93 18 — 35 146 38,173 Indirect installment 311,494 1,396 198 173 916 2,683 314,177 Home equity 192,162 761 37 7 1,799 2,604 194,766 Total consumer 541,794 2,250 253 180 2,750 5,433 547,116 Total $ 2,996,548 $ 5,100 $ 2,061 $ 568 $ 12,605 $ 20,334 $ 3,016,771 Percentage of total loans 99.33 % 0.17 % 0.07 % 0.02 % 0.42 % 0.67 % 100.00 % The entire balance of a loan is considered delinquent if the minimum payment contractually required to be made is not received by the specified due date. Horizon Bank’s processes for determining credit quality differ slightly depending on whether a new loan or a renewed loan is being underwritten, or whether an existing loan is being re-evaluated • For new and renewed commercial loans, the Bank’s Credit Department, which acts independently of the loan officer, assigns the credit quality grade to the loan. Loan grades for loans with an aggregate credit exposure that exceeds the authorities in the respective markets (ranging from $1,000,000 to $3,500,000) are validated by the Loan Committee, which is chaired by the Chief Commercial Banking Officer (CCBO). • Commercial loan officers are responsible for reviewing their loan portfolios and reporting any adverse material change to the CCBO or Loan Committee. When circumstances warrant a change in the credit quality grade, loan officers are required to notify the CCBO and the Credit Department of the change in the loan grade. Downgrades are accepted immediately by the CCBO, however, lenders must present their factual information to either the Loan Committee or the CCBO when recommending an upgrade. • The CCBO, or his designee, meets regularly with loan officers to discuss the status of past-due • Monthly, senior management meets with the Watch Committee, which reviews all of the past due, classified, and impaired loans and the relative trends of these assets. This committee also reviews the actions taken by management regarding foreclosure mitigation, loan extensions, troubled debt restructures, other real estate owned and personal property repossessions. The information reviewed in this meeting acts as a precursor for developing management’s analysis of the adequacy of the Allowance for Loan and Lease Losses. For residential real estate and consumer loans, Horizon uses a grading system based on delinquency. Loans that are 90 days or more past due, on non-accrual, non-accrual. Risk Grade 1: Excellent (Pass) Loans secured by liquid collateral, such as certificates of deposit, reputable bank letters of credit, or other cash equivalents; loans that are guaranteed or otherwise backed by the full faith and credit of the United States government or an agency thereof, such as the Small Business Administration; or loans to any publicly held company with a current long-term debt rating of A or better. Risk Grade 2: Good (Pass) Loans to businesses that have strong financial statements containing an unqualified opinion from a CPA firm and at least three consecutive years of profits; loans supported by unaudited financial statements containing strong balance sheets, five consecutive years of profits, a five -year satisfactory relationship with the Bank, and key balance sheet and income statement trends that are either stable or positive; loans secured by publicly traded marketable securities where there is no impediment to liquidation; loans to individuals backed by liquid personal assets and unblemished credit history; or loans to publicly held companies with current long-term debt ratings of Baa or better. Risk Grade 3: Satisfactory (Pass) Loans supported by financial statements (audited or unaudited) that indicate average or slightly below average risk and having some deficiency or vulnerability to changing economic conditions; loans with some weakness but offsetting features of other support are readily available; loans that are meeting the terms of repayment, but which may be susceptible to deterioration if adverse factors are encountered. Loans may be graded Satisfactory when there is no recent information on which to base a current risk evaluation and the following conditions apply: • At inception, the loan was properly underwritten, did not • At inception, the loan was secured with collateral possessing a loan value adequate to protect the Bank from loss. • The loan has exhibited two or more years of satisfactory repayment with a reasonable reduction of the principal balance. • During the period that the loan has been outstanding, there has been no evidence of any credit weakness. Some examples of weakness include slow payment, lack of cooperation by the borrower, breach of loan covenants, or the borrower is in an industry known to be experiencing problems. If any of these credit weaknesses is observed, a lower risk grade may be warranted. Risk Grade 4 Satisfactory/Monitored: Loans in this category are considered to be of acceptable credit quality, but contain greater credit risk than Satisfactory loans. Borrower displays acceptable liquidity, leverage, and earnings performance within the Bank’s minimum underwriting guidelines. The level of risk is acceptable but conditioned on the proper level of loan officer supervision. Loans that normally fall into this grade include acquisition, construction and development loans and income producing properties that have not reached stabilization. Risk Grade 4W Management Watch: Loans in this category are considered to be of acceptable quality, but with above normal risk. Borrower displays potential indicators of weakness in the primary source of repayment resulting in a higher reliance on secondary sources of repayment. Balance sheet may exhibit weak liquidity and/or high leverage. There is inconsistent earnings performance without the ability to sustain adverse economic conditions. Borrower may be operating in a declining industry or the property type, as for a commercial real estate loan, may be unstablized, high risk or in decline. These loans require an increased level of loan officer supervision and monitoring to assure that any deterioration is addressed in a timely fashion. Risk Grade 5: Special Mention Loans which possess some credit deficiency or potential weakness which deserves close attention. Such loans pose an unwarranted financial risk that, if not corrected, could weaken the loan by adversely impacting the future repayment ability of the borrower. The key distinctions of a Special Mention classification are that (1) it is indicative of an unwarranted level of risk and (2) weaknesses are considered “potential,” not “defined,” impairments to the primary source of repayment. These loans may be to borrowers with adverse trends in financial performance, collateral value and/or marketability, or balance sheet strength. Risk Grade 6: Substandard One or more of the following characteristics may be exhibited in loans classified Substandard: • Loans which possess a defined credit weakness. The likelihood that a loan will be paid from the primary source of repayment is uncertain. Financial deterioration is under way and very close attention is warranted to ensure that the loan is collected without loss. • Loans are inadequately protected by the current net worth and paying capacity of the obligor. • The primary source of repayment is gone, and the Bank is forced to rely on a secondary source of repayment, such as collateral liquidation or guarantees. • Loans have a distinct possibility that the Bank will sustain some loss if deficiencies are not corrected. • Unusual courses of action are needed to maintain a high probability of repayment. • The borrower is not generating enough cash flow to repay loan principal; however, it continues to make interest payments. • The lender is forced into a subordinated or unsecured position due to flaws in documentation. • Loans have been restructured so that payment schedules, terms, and collateral represent concessions to the borrower when compared to the normal loan terms. Risk Grade 8: Loss Loans are considered uncollectible and of such little value that continuing to carry them as assets is not feasible. Loans will be classified Loss when it is neither practical nor desirable to defer writing off or reserving all or a portion of a basically worthless asset, even though partial recovery may be possible at some time in the future.

Leases [Abstract]
Leases	Note 8 – Leases As of January 1, 2019, when the Company adopted ASU 2016-02 prospectively, the Company began recording operating leases as a right-of-use (“ROU”) asset in other assets and operating lease liability in other liabilities on the consolidated balance sheet. Operating lease ROU assets represent the right to use an underlying asset during the lease term and operating lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and operating lease liabilities are recognized at lease commencement based on the present value of the remaining lease payments using a discount rate that represents our incremental borrowing rate at the lease commencement date. Operating lease expense, which is comprised of amortization of the ROU asset and the implicit interest accreted on the operating liability, is recognized on a straight-line basis over the lease term, and is recorded primarily in net occupancy expense in the consolidated statements of income. When the Company adopted the guidance on January 1, 2019, it elected the optional alternative transition method permitted by ASU 2018-11 allowing for recognition of applicable leases as of January 1, 2019. Additionally, the Company elected the following accounting policies: • The practical expedient package that forgoes: • Reassessment of any expired or existing contracts for a lease • Reassessment of lease classification for expired or existing leases • Reassessment of initial direct costs for existing leases • The hindsight practical expedient to determine lease term and impairment of ROU assets • Other practical expedients regarding combination of lease and non-lease • The Company did not elect to follow the practical expedients for land easements and the portfolio approach Operating leases relate primarily to bank branches and office space with remaining average lease terms of seven years. The weighted average discount rate utilized to calculate the ROU asset and operating lease liability was approximately 2.57%, which represents the incremental borrowing rate. At inception, the Company recorded a ROU asset and operating lease liability of $3.4 million. At June 30, 2019, a ROU asset of $3.1 million is included in other assets and an operating lease liability of $3.3 million is included in other liabilities. Options to extend a lease were considered in the remaining lease term determination. The lease expense for operating leases was $149,000 for the three months ended June 30, 2019 and $297,000 for the six months ended June 30, 2019. Future minimum operating lease payments under non-cancellable Year Amount 2019 $ 240 2020 476 2021 476 2022 504 2023 and thereafter 1,609 Total lease payments $ 3,305 Less: Interest (175 ) Present value of lease liabilities $ 3,130

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Note 10 – Derivative Financial Instruments Cash Flow Hedges – The Company assumed additional interest rate swap agreements as the result of the LaPorte acquisition in July 2016. The agreements provide for the Company to receive interest from the counterparty at one month LIBOR and to pay interest to the counterparty at a weighted average fixed rate of 2.31% on a notional amount of $30.0 million at June 30, 2019 and December 31, 2018. Under the agreements, the Company pays or receives the net interest amount monthly, with the monthly settlements included in interest expense. On July 20, 2018, the Company entered into an interest rate swap agreement for an additional portion of its floating rate debt. The agreement provides for the Company to receive interest from the counterparty at one month LIBOR and to pay interest to the counterparty at a rate of 2.81% on a notional amount of $50.0 million at June 30, 2019 Under the agreement, the Company pays or receives the net interest amount monthly, with the monthly settlements included in interest expense. Management has designated the interest rate swap agreement as a cash flow hedging instrument. For derivative instruments that are designated and qualify as a cash flow hedge, the effective portion of the gain or loss on the derivative is reported as a component of other comprehensive income and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current earnings. At June 30, 2019, the Company’s cash flow hedge was effective and is not expected to have a significant impact on the Company’s net income over the next 12 months. Fair Value Hedges Fair value hedges are intended to reduce the interest rate risk associated with the underlying hedged item. The Company enters into fixed rate loan agreements as part of its lending policy. To mitigate the risk of changes in fair value based on fluctuations in interest rates, the Company has entered into interest rate swap agreements on individual loans, converting the fixed rate loans to a variable rate. For derivative instruments that are designated and qualify as a fair value hedge, the gain or loss on the derivative as well as the offsetting gain or loss on the hedged item attributable to the hedged risk are recognized in current earnings. At June 30, 2019, the Company’s fair value hedges were effective and are not expected to have a significant impact on the Company’s net income over the next 12 months. The change in fair value of both the hedge instruments and the underlying loan agreements are recorded as gains or losses in interest income. The fair value hedges are considered to be highly effective and any hedge ineffectiveness was deemed not material.

Disclosures about fair value of assets and liabilities	Note 11 – Disclosures about Fair Value of Assets and Liabilities The Fair Value Measurements topic of the FASB ASC defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. There are three levels of inputs that may be used to measure fair value: Level 1 Quoted prices in active markets for identical assets or liabilities Level 2 Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities Level 3 Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities Following is a description of the valuation methodologies used for instruments measured at fair value on a recurring basis and recognized in the accompanying condensed consolidated financial statements, as well as the general classification of such instruments pursuant to the valuation hierarchy. There have been no significant changes in the valuation techniques during the period ended June 30, 2019. For assets classified within Level 3 of the fair value hierarchy, the process used to develop the reported fair value is described below. Available for sale securities When quoted market prices are available in an active market, securities are classified within Level 1 of the valuation hierarchy. If quoted market prices are not available, then fair values are estimated by using pricing models, quoted prices of securities with similar characteristics or discounted cash flows. Level 2 securities include U.S. Treasury and federal agency securities, state and municipal securities, federal agency collateralized mortgage obligations and mortgage-backed pools and corporate notes. Level 2 securities are valued by a third party pricing service commonly used in the banking industry utilizing observable inputs. Observable inputs include dealer quotes, market spreads, cash flow analysis, the U.S. Treasury yield curve, trade execution data, market consensus prepayment spreads and available credit information and the bond’s terms and conditions. The pricing provider utilizes evaluated pricing models that vary based on asset class. These models incorporate available market information including quoted prices of securities with similar characteristics and, because many fixed-income securities do not trade on a daily basis, apply available information through processes such as benchmark curves, benchmarking of like securities, sector grouping, and matrix pricing. In addition, model processes, such as an option adjusted spread model, is used to develop prepayment and interest rate scenarios for securities with prepayment features. Hedged loans Certain fixed rate loans have been converted to variable rate loans by entering into interest rate swap agreements. The fair value of those fixed rate loans is based on discounting the estimated cash flows using interest rates determined by the respective interest rate swap agreement. Loans are classified within Level 2 of the valuation hierarchy based on the unobservable inputs used. Interest rate swap agreements The fair value of the Company’s interest rate swap agreements is estimated by a third party using inputs that are primarily unobservable including a yield curve, adjusted for liquidity and credit risk, contracted terms and discounted cash flow analysis, and therefore, are classified within Level 2 of the valuation hierarchy. The following table presents the fair value measurements of assets and liabilities recognized in the accompanying condensed consolidated financial statements measured at fair value on a recurring basis and the level within the FASB ASC fair value hierarchy in which the fair value measurements fall at the following: June 30, 2019 Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Available for sale securities U.S. Treasury and federal agencies $ 9,901 $ — $ 9,901 $ — State and municipal 260,165 — 260,165 — Federal agency collateralized mortgage obligations 231,522 — 231,522 — Federal agency mortgage-backed pools 153,523 — 153,523 — Corporate notes 18,308 — 18,308 — Total available for sale securities 673,419 — 673,419 — Hedged loans 258,180 — 258,180 — Forward sale commitments 467 — 467 — Interest rate swap agreements (16,389 ) — (16,389 ) — Commitments to originate loans — — — — December 31, 2018 Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Available for sale securities U.S. Treasury and federal agencies $ 16,608 $ — $ 16,608 $ — State and municipal 209,303 — 209,303 — Federal agency collateralized mortgage obligations 185,003 — 185,003 — Federal agency mortgage-backed pools 178,736 — 178,736 — Corporate notes 10,698 — 10,698 — Total available for sale securities 600,348 — 600,348 — Hedged loans 209,161 — 209,161 — Forward sale commitments 135 — 135 — Interest rate swap agreements (1,801 ) — (1,801 ) — Commitments to originate loans — — — — Realized gains and losses included in net income for the periods are reported in the condensed consolidated statements of income as follows: Non-interest Three Months Ended Six Months Ended Total gains and losses from: June 30, 2019 June 30, 2018 June 30, 2019 June 30, 2018 Hedged loans $ (7,529 ) $ 976 $ (11,580 ) $ 3,744 Fair value interest rate swap agreements 7,529 (976 ) 11,580 (3,744 ) Derivative loan commitments 75 71 332 183 $ 75 $ 71 $ 332 $ 183 Certain other assets are measured at fair value on a non-recurring Fair Value Quoted Prices in (Level 1) Significant Significant (Level 3) June 30, 2019 Impaired loans $ 7,847 $ — $ — $ 7,847 Mortgage servicing rights 13,652 — — 13,652 December 31, 2018 Impaired loans $ 5,661 $ — $ — $ 5,661 Mortgage servicing rights 12,349 — — 12,349 Impaired (collateral dependent): If the impaired loan is identified as collateral dependent, then the fair value method of measuring the amount of impairment is utilized.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Note 12 – Fair Value of Financial Instruments The estimated fair value amounts of the Company’s financial instruments were determined using available market information, current pricing information applicable to Horizon and various valuation methodologies. Where market quotations were not available, considerable management judgment was involved in the determination of estimated fair values. Therefore, the estimated fair value of financial instruments shown below may not be representative of the amounts at which they could be exchanged in a current or future transaction. Due to the inherent uncertainties of expected cash flows of financial instruments, the use of alternate valuation assumptions and methods could have a significant effect on the estimated fair value amounts. The estimated fair values of financial instruments, as shown below, are not intended to reflect the estimated liquidation or market value of Horizon taken as a whole. The disclosed fair value estimates are limited to Horizon’s significant financial instruments at June 30, 2019 and December 31, 2018. These include financial instruments recognized as assets and liabilities on the condensed consolidated balance sheet as well as certain off-balance The following methods and assumptions were used to estimate the fair value of each class of financial instrument: Cash and Due from Banks Held-to-Maturity Securities Loans Held for Sale Net Loans FHLB Stock Interest Receivable/Payable Deposits Borrowings Subordinated Debentures Commitments to Extend Credit and Standby Letters of Credit The following table presents estimated fair values of the Company’s financial instruments and the level within the fair value hierarchy in which the fair value measurements fall (unaudited).

Banking and Thrift [Abstract]
Regulatory Capital	Note 14 – Regulatory Capital Horizon and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. These capital requirements implement changes arising from the Dodd-Frank Wall Street Reform and Consumer Protection Act and the U.S. Basel Committee on Banking Supervision’s capital framework (known as “Basel III”). Failure to meet the minimum regulatory capital requirements can initiate certain mandatory and possible additional discretionary actions by regulators, which if undertaken, could have a direct material effect on the Company’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective actions, the Company and Bank must meet specific capital guidelines involving quantitative measures of the Bank’s assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. The Company’s and Bank’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. The Company and Bank are subject to minimum regulatory capital requirements as defined and calculated in accordance with the Basel III-based regulations. As allowed under Basel III rules, the Company made the decision to opt-out of including accumulated other comprehensive income in regulatory capital. The minimum regulatory capital requirements are set forth in the table below. In addition, to be categorized as well capitalized, the Company and Bank must maintain Total risk-based, Tier I risk-based, common equity Tier I risk-based and Tier I leverage ratios as set forth in the table below. As of June 30, 2019 and December 31, 2018, the Company and Bank met all capital adequacy requirements to be considered well capitalized. There have been no conditions or events since the end of the second quarter of 2019 that management believes have changed the Bank’s classification as well capitalized. There is no threshold for well-capitalized status for bank holding companies. Horizon and the Bank’s actual and required capital ratios as of June 30, 2019 and December 31, 2018 were as follows: Actual Required for Capital 1 Required For Capital 1 Well Capitalized Under 1 Amount Ratio Amount Ratio Amount Ratio Amount Ratio June 30, 2019 Total capital 1 Consolidated $ 519,613 13.23 % $ 314,113 8.00 % $ 412,273 10.50 % N/A N/A Bank 480,366 12.23 % 314,242 8.00 % 412,443 10.50 % $ 392,802 10.00 % Tier 1 capital 1 Consolidated 501,272 12.77 % 235,586 6.00 % 333,747 8.50 % N/A N/A Bank 462,025 11.76 % 235,681 6.00 % 333,881 8.50 % 314,241 8.00 % Common equity tier 1 capital 1 Consolidated 443,779 11.30 % 176,689 4.50 % 274,849 7.00 % N/A N/A Bank 462,025 11.76 % 176,761 4.50 % 274,961 7.00 % 255,321 6.50 % Tier 1 capital 1 Consolidated 501,272 10.33 % 194,081 4.00 % 194,081 4.00 % N/A N/A Bank 462,025 9.52 % 194,081 4.00 % 194,081 4.00 % 242,602 5.00 % December 31, 2018 Total capital 1 Consolidated $ 427,616 13.39 % $ 255,419 8.00 % $ 315,283 9.875 % N/A N/A Bank 396,755 12.43 % 255,419 8.00 % 315,283 9.875 % $ 319,274 10.00 % Tier 1 capital 1 Consolidated 409,760 12.83 % 191,565 6.00 % 251,429 7.875 % N/A N/A Bank 378,899 11.87 % 191,565 6.00 % 251,429 7.875 % 255,420 8.00 % Common equity tier 1 capital 1 Consolidated 371,297 11.63 % 143,673 4.50 % 203,537 6.375 % N/A N/A Bank 378,899 11.87 % 143,674 4.50 % 203,537 6.375 % 207,528 6.50 % Tier 1 capital 1 Consolidated 409,760 10.12 % 162,033 4.00 % 162,033 4.000 % N/A N/A Bank 378,899 9.34 % 162,327 4.00 % 162,327 4.000 % 202,908 5.00 %

Accounting Changes and Error Corrections [Abstract]
Future Accounting Matters	Note 15 – Future Accounting Matters Financial Accounting Standards Board (FASB) Accounting Standards Update (ASU) No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement The FASB has issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement . These amendments modify the disclosure requirements in Topic 820 as follows: Removals : the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy; the policy for timing of transfers between levels; and the valuation processes for Level 3 fair value measurements. Modifications : for investments in certain entities that calculate net asset value, an entity is required to disclose the timing of liquidation of an investee’s assets and the date when restrictions from redemption might lapse only if the investee has communicated the timing to the entity or announced the timing publicly; and the amendments clarify that the measurement uncertainty disclosure is to communicate information about the uncertainty in measurement as of the reporting date. Additions : the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period; and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The guidance is effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should all be applied prospectively for only the most recent interim or annual period presented in the initial year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. Early adoption is permitted. An entity is permitted to early adopt any removed or modified disclosures upon issuance of ASU No. 2018-13 and delay adoption of the additional disclosures until their effective date. We are currently evaluating the impact of adoption of ASU 2018-13 and the impact on our accounting and disclosures. FASB ASU No. 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment The FASB has issued ASU No. 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The new guidance is intended to simplify the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. The annual, or interim, goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount. An impairment charge should be recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. In addition, the income tax effects of tax deductible goodwill on the carrying amount of the reporting unit should be considered when measuring the goodwill impairment loss, if applicable. The amendments also eliminate the requirements for any reporting unit with a zero or negative carrying amount to perform Step 2 of the goodwill impairment test. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the qualitative impairment test is necessary. The amendments should be applied on a prospective basis. The nature of and reason for the change in accounting principle should be disclosed upon transition. The amendments in this update should be adopted for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted on testing dates after January 1, 2017. We are currently evaluating the impact of adopting the new guidance on the consolidated financial statements, but it is not expected to have a material impact. FASB ASU No. 2016-13, Financial Instruments – Credit Losses Measurement of Credit Losses on Financial Instruments The FASB has issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The main objective of this amendment is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. The amendment requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to enhance their credit loss estimates. The amendment requires enhanced disclosures to help investors and other financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s portfolio. In addition, the ASU amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The amendments in this update become effective for annual periods and interim periods within those annual periods beginning after December 15, 2019. Early adoption will be permitted beginning after December 15, 2018. We expect a one-time cumulative-effect adjustment to the allowance for loan losses will be recognized in retained earnings on the consolidated balance sheet as of the beginning of the first reporting period in which the new standard is effective, as is consistent with regulatory expectations set forth in interagency guidance issued at the end of 2016. We are currently implementing third-party software that was purchased and are validating the data loaded into the solution. Our implementation team meets on a regular basis to oversee activities and monitor progress. The methodologies are in the process of being finalized so the magnitude of any such adjustment or the overall impact of the new standard on the financial condition or results of operations cannot yet be determined.
