Business. (Dollars in thousands) General PART I Isabella Bank Corporation is a registered financial services holding company that was incorporated in September 1988 under Michigan law. The Corporation's wholly owned subsidiary, Isabella Bank, has 30 banking offices located throughout Clare, Gratiot, Isabella, Mecosta, Midland, Montcalm, and Saginaw counties. The area includes significant agricultural production, manufacturing, retail, gaming and tourism, and several colleges and universities. As used in Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations as well as in Item 8. Financial Statements and Supplementary Data, references to “the Corporation”, “Isabella”, “we”, “our”, “us”, and similar terms refer to the consolidated entity consisting of Isabella Bank Corporation and its subsidiary. References to Isabella Bank or the “Bank” refers to Isabella Bank Corporation’s subsidiary, Isabella Bank. We are a community bank with a focus on providing high quality, personalized service at a fair price. We offer a broad array of banking and wealth management services to businesses, institutions, individuals and their families. We compete with other commercial banks, savings and loan associations, mortgage brokers, finance companies, credit unions, retail brokerage firms, and other companies providing financial services. Lending activities include loans for commercial and agricultural operations and real estate purposes, residential real estate loans, and consumer loans. We limit lending activities primarily to local markets and purchased loans from the secondary market are minimal. We do not make loans to fund leveraged buyouts, have no foreign corporate or government loans, and have limited holdings of corporate debt securities. Our general lending philosophy is to limit concentrations to individuals and business segments. For additional information related to our lending strategies and policies, see “Note 4 – Loans and ALLL” of “Notes to Consolidated Financial Statements” in Item 8. Financial Statements and Supplementary Data. Deposit services offered include checking accounts, savings accounts, certificates of deposit, direct deposits, cash management services, mobile and internet banking, electronic bill pay services, and automated teller machines. We also offer full service investment management, trust and estate services. As of December 31, 2020, we had 340 full-time equivalent employees. We provide group life, health, accident, disability, and other insurance programs as well as a number of other employee benefit programs. None of our workforce is subject to collective bargaining agreements. Available Information Our SEC filings (including our Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, Definitive Proxy Statements, Current Reports on Form 8-K and amendments to those reports) are available through our website (www.isabellabank.com). We will provide paper copies of our SEC reports free of charge upon request by a shareholder. The SEC maintains a website (www.sec.gov) that contains reports, proxy and information statements and other information regarding Isabella Bank Corporation (CIK #0000842517) and other issuers. Supervision and Regulation The earnings and growth of the banking industry are affected by the credit policies of monetary authorities, including the FRB. An important function of the FRB is to regulate the national supply of bank credit in order to combat recessions and respond to inflationary pressures. Among the instruments of monetary policy used by the FRB to implement these objectives are open market operations in U.S. Treasury and U.S. Government Agency securities, changes in the discount rate on member bank borrowings, and changes in reserve requirements against member bank deposits. These methods are used in varying combinations to influence overall growth of bank loans, investments and deposits and also affect interest rates charged on loans or paid for deposits. The monetary policies of the FRB have had a significant effect on the operating results of commercial banks and related financial service providers in the past and are expected to continue to do so in the future. The effect of such policies upon our future business and earnings cannot be predicted. We, as a financial holding company, are regulated under the BHC Act, and are subject to the supervision of the FRB. We are registered as a financial services holding company with the FRB and are subject to reporting requirements and inspections and audits. Under FRB policy, we are expected to act as a source of financial strength to the Bank and to commit resources to support its subsidiaries. This support may be required at times when, in the absence of such FRB policy, it would not otherwise be required to provide support. 4 Table of Contents Under Michigan law, if the capital of a Michigan state chartered bank has become impaired by losses or otherwise, the Commissioner of the DIFS may require that the deficiency in capital be met by assessment upon the bank’s shareholders. Each shareholder would be responsible for a pro rata share of the deficiency, based on the amount of capital stock held by each shareholder. If an assessment is not paid by any shareholder within 30 days of the date of notice to the shareholder, sale of their stock will occur in order to pay such assessment. Any capital loans by a bank holding company to any of its subsidiary banks are subordinate in right of payment to deposits and to certain other indebtedness of such subsidiary bank. In the event of a bank holding company’s bankruptcy, any commitment by the bank holding company to a federal bank regulatory agency to maintain the capital of a subsidiary bank will be assumed by the bankruptcy trustee and entitled to a priority of payment. This priority would apply to guarantees of capital plans under the FDIC Improvement Act of 1991. SOX contains important requirements for public companies in the area of financial disclosure and corporate governance. In accordance with Section 302(a) of SOX, written certifications by our principal executive, financial, and accounting officers are required. These certifications attest that our quarterly and annual reports filed with the SEC do not contain any untrue statement of a material fact (see the certifications filed as Exhibits 31 (a) and (b) to this Form 10-K for such certification of consolidated financial statements and other information for this 2020 Form 10-K). We have also implemented a program designed to comply with Section 404 of SOX, which included the identification of significant processes and accounts, documentation of the design effectiveness over process and entity level controls, and testing of the operating effectiveness of key controls. See Item 9A. Controls and Procedures for our evaluation of disclosure controls and procedures and internal control over financial reporting. Certain additional information concerning regulatory guidelines for capital adequacy and other regulatory matters is presented herein under the caption “Capital” in Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations and in “Note 10 – Off-Balance-Sheet Activities, Commitments and Other Matters” and “Note 11 – Minimum Regulatory Capital Requirements” of “Notes to Consolidated Financial Statements” in Item 8. Financial Statements and Supplementary Data. Isabella Bank The Bank is supervised and regulated by DIFS and the FRB. These agencies and federal and state laws extensively regulate various aspects of the banking business including, among other things, permissible types and amounts of loans, investments and other activities, capital adequacy, branching, interest rates on loans and deposits, and the safety and soundness of banking practices. Our deposits are insured up to applicable limits by the DIF of the FDIC and are subject to deposit insurance assessments to maintain the DIF. The FDIC assesses insurance premiums based upon a financial ratios method that takes into account asset and capital levels and supervisory ratings. Banking laws and regulations restrict transactions by insured banks owned by a bank holding company. These restrictions include loans to and certain purchases from the parent holding company, non-bank and bank subsidiaries of the parent holding company. Additional restrictions apply to principal shareholders, officers, directors and their affiliates, and investments by the subsidiary bank in the shares or securities of the parent holding company (or any of the other non-bank or bank affiliates), or acceptance of such shares or securities as collateral security for loans to any borrower. The Bank is subject to legal limitations on the frequency and amount of dividends that can be paid to Isabella Bank Corporation. For example, a Michigan state chartered bank may not declare a cash dividend or a dividend in kind except out of net profits then on hand after deducting all losses and bad debts, and then only if it will have a surplus amounting to not less than 20% of its capital after the payment of the dividend. Moreover, a Michigan state chartered bank may not declare or pay any cash dividend or dividend in kind until the cumulative dividends on its preferred stock, if any, have been paid in full. Further, if the surplus of a Michigan state chartered bank is at any time less than the amount of its capital, before the declaration of a cash dividend or dividend in kind, it must transfer to surplus not less than 10% of its net profits for the preceding six months (in the case of quarterly or semi-annual dividends) or the preceding two consecutive six month periods (in the case of annual dividends). The payment of dividends by Isabella Bank Corporation and the Bank is also affected by various regulatory requirements and policies, such as the requirement to keep adequate capital in compliance with regulatory guidelines. Federal laws impose further restrictions on the payment of dividends by insured banks that fail to meet specified capital levels. The FDIC may prevent an insured bank from paying dividends if the bank is in default of payment of any assessment due to the FDIC. In addition, payment of dividends by a bank may be prevented by the applicable federal regulatory authority if such payment is determined, by reason of the financial condition of such bank, to be an unsafe and unsound banking practice. The FRB and the 5 Table of Contents FDIC have issued policy statements providing that bank holding companies and insured banks should generally pay dividends only out of current operating earnings. Additionally, the FRB Board of Governors requires a bank holding company to notify the FRB prior to increasing its cash dividend by more than 10% over the prior year. The aforementioned regulations and restrictions may limit our ability to obtain funds from the Bank for our cash needs, including payment of dividends and operating expenses. The activities and operations of the Bank are also subject to various federal and state laws and regulations. Item 1A. Risk Factors. In the normal course of business, we are exposed to various risks. These risks, if not managed correctly, could have a significant impact on our earnings, capital, share price, and ability to pay dividends. In order to effectively monitor and control the following risks, we utilize an enterprise risk model. We balance our strategic goals, including revenue and profitability objectives, with associated risks through the use of policies, systems, and procedures which have been adopted to identify, assess, control, monitor, and manage each risk area. We continually review the adequacy and effectiveness of these policies, systems, and procedures. Our enterprise risk process covers each of the following areas. The COVID-19 pandemic may adversely affect our business Unexpected and unprecedented changes have occurred during 2020 and into 2021 as the result of COVID-19. This aggressive and persistent virus causes a respiratory disease and can result in serious illness or death. The World Health Organization has declared the situation a global pandemic. The pandemic has created significant market volatility, economic uncertainty, and disruption to normal business operations around the world, with slowdowns and shutdowns affecting entire industries. The Michigan governor issued on March 23, 2020 a stay-at-home order, which limited gatherings and travel, and required those working, or required individuals working in select businesses who were not deemed essential to sustain or protect life to stay home. The Michigan stay-at- home order was in effect until early June. The orders led to financial stress for many businesses and their employees throughout the communities we serve. Additional executive and Michigan State Health Department orders have been put in place since June 2020. The extent to which COVID-19 impacts our business will depend on future developments, which are highly uncertain and cannot be predicted with any accuracy. Future developments include new information which may emerge concerning the severity of COVID-19 and the actions to contain the coronavirus or treat its impact, among others. We expect the significance of the COVID-19 pandemic, including the extent of its effect on our financial and operational results, to be dictated by, among other factors, its duration, the success of efforts to contain it and the impact of actions taken in response, including the development and distribution of effective vaccines. Uncertainty created by the COVID-19 pandemic is pervasive, and has impacted our financial results, operations, customers, vendors and various areas of risk. Areas of risk may include, but are not limited to, cybersecurity, credit, interest rate, litigation and risk related to vendor services. With the uncertainty created by COVID-19, it's challenging to determine the full impact on our ongoing financial and operational results. We continue to closely monitor external events and are in continual discussion with our customers to assess, prepare and respond to conditions as they evolve. Changes in credit quality and required allowance for loan and lease losses To manage the credit risk arising from lending activities, our most significant source of credit risk, we maintain sound underwriting policies and procedures. We continuously monitor asset quality in order to determine the appropriateness of valuation allowances. These valuation allowances take into consideration various factors including, but not limited to, local, regional, and national economic conditions. We maintain an ALLL to reserve for estimated incurred loan losses within our loan portfolio. The level of the ALLL reflects our evaluation of industry concentrations; specific credit risks; loan loss experience; loan portfolio quality; and economic, political and regulatory conditions. The determination of the appropriate level of the ALLL inherently involves a high degree of subjectivity and requires us to make significant estimates, all of which may undergo material changes. Changes in economic conditions An economic downturn within our local markets, as well as downturns in the state, national, or global markets, could negatively impact household and corporate incomes. This could lead to decreased demand for both loan and deposit products and lead to 6 Table of Contents an increase of customers who fail to pay interest or principal on their loans. We continually monitor key economic indicators in an effort to anticipate the possible effects of downturns in the local, regional, and national economies. Our success depends primarily on the general economic conditions of the State of Michigan and the specific local markets in which we operate. We provide banking and financial services to customers located primarily in the Clare, Gratiot, Isabella, Mecosta, Midland, Montcalm, and Saginaw counties in Michigan. The local economic conditions in these areas have a significant impact on the demand for our products and services, as well as the ability of our customers to repay loans, the value of the collateral securing loans, and the stability of our deposit funding sources. A significant decline in general economic conditions, caused by inflation, recession, acts of terrorism, international or domestic occurrences, a health crisis, unemployment, changes in securities markets or other factors could impact these local economic conditions and, in turn, could have a material adverse effect on our financial condition and results of operations. Interest rate risk IRR results from the timing differences in the maturity or repricing frequency of a financial institution’s interest earning assets and its interest bearing liabilities. We monitor the potential effects of changes in interest rates through simulations and gap analyses. To help mitigate the effects of changes in interest rates, we make significant efforts to stagger projected cash flows and maturities of interest sensitive assets and liabilities. Liquidity risk Liquidity risk is the risk to earnings or capital arising from our inability to meet our obligations when they come due without incurring unacceptable and significant costs. Liquidity risk includes the inability to manage unplanned changes in funding sources, or failure to address changes in market conditions that affect the ability to liquidate assets quickly and with minimal loss in value. We have significant borrowing capacity through correspondent banks and the ability to sell certain investments to fund potential cash shortages, which we may use to help mitigate this risk. The value of investment securities may be negatively impacted by fluctuations in the market A volatile, illiquid market or decline in credit quality could require us to recognize an OTTI loss related to the investment securities held in our portfolio. We consider many factors in determining whether an OTTI exists including the length of time and extent to which fair value has been less than cost, the investment credit rating, and the probability that the issuer will be unable to pay the amount when due. The presence of these factors could lead to impairment charges. These risks are mitigated by the fact that we do not intend to sell the security in an unrealized loss position and it is more likely than not that we will not have to sell the security before recovery of its cost basis. Operational risk Operational risk is the risk of loss resulting from failed or inadequate internal processes, staffing, systems, or external events and includes reputation risk and transaction risk. Reputation risk is managed by developing and retaining marketplace confidence in handling customers’ financial transactions in an appropriate manner and protecting our safety and soundness. Transaction risk includes losses from fraud, error, the inability to deliver products or services, and loss or theft of information. Transaction risk also encompasses product development and delivery, transaction processing, information technology systems, and the internal control environment. To minimize potential losses due to operational risks, we have established a robust system of internal controls that are regularly tested by our internal audit department in conjunction with the services of certified public accounting firms who assist in performing such internal audit work. The focus of these internal audit procedures is to verify the validity and appropriateness of various transactions, processes, and controls. The results of these procedures are reported to our Audit Committee. The adoption of, violations of, or nonconformance with laws, rules, regulations, or prescribed practices The financial services industry and public companies are extensively regulated and must meet regulatory standards set by the FDIC, DIFS, FRB, FASB, SEC, PCAOB, CFPB, and other regulatory bodies. Federal and state laws and regulations are designed primarily to protect deposit insurance funds and consumers, and not necessarily to benefit our shareholders. The nature, extent, and timing of the adoption of significant new laws, changes in existing laws, or repeal of existing laws may have a material impact on our business, results of operations, and financial condition, the effect of which is impossible to predict at this time. Our compliance department annually assesses the adequacy and effectiveness of our processes for controlling and managing our principal compliance risks. 7 Table of Contents Changes to the financial services industry as a result of regulatory changes or actions, or significant litigation The financial services industry is extensively regulated by state and federal regulation that governs almost all aspects of our operations. Laws and regulations may change from time to time and are primarily intended for the protection of consumers, depositors, and the deposit insurance fund. The impact of any changes to laws and regulations or other actions by regulatory agencies may negatively impact us or our ability to increase the value of our business. Regulatory authorities have extensive discretion in connection with their supervisory and enforcement activities, including the imposition of restrictions on the operation of an institution, the classification of assets by the institution, and the appropriateness of an institution’s ALLL. Future regulatory changes or accounting pronouncements may increase our regulatory capital requirements or adversely affect our regulatory capital levels. Additionally, actions by regulatory agencies or significant litigation against us could require the dedication of significant time and resources to defend our business and may lead to penalties. We may not adjust to changes in the financial services industry Our financial performance depends in part on our ability to maintain and grow our core deposit customer base and expand our financial services to our existing and new customers. The increasingly competitive environment is, in part, a result of changes in technology and product delivery systems and the accelerating pace of consolidation among financial service providers. New competitors may emerge to increase the degree of competition for our products and services. Financial services and products are also constantly changing. Our financial performance is dependent upon customer demand for our products and services, our ability to develop and offer competitive financial products and services, and our ability to adapt to enhancements in financial technology. We may be required to recognize an impairment of goodwill Goodwill represents the excess of the amounts paid to acquire subsidiaries over the fair value of their net assets at the date of acquisition. The majority of the recorded goodwill is related to acquisitions of other banks, which were subsequently merged into Isabella Bank. If it is determined that the goodwill is impaired, we must write-down the goodwill by the amount of the impairment. We may face pressure from purchasers of our residential mortgage loans to repurchase loans sold or reimburse purchasers for losses related to such loans We generally sell the fixed rate long-term residential mortgage loans we originate to the secondary market. The purchasers of residential mortgage loans, such as government sponsored entities, increased their efforts to require sellers of residential mortgage loans to either repurchase loans previously sold, or reimburse the purchasers for losses incurred on foreclosed loans due to actual or alleged failure to strictly conform to the terms of the contract. Consumers may decide not to use banks to complete their financial transactions Technology and other changes are allowing customers to complete financial transactions without the involvement of banks. For example, consumers can now pay bills and transfer funds directly without banks. The process of diminishing or removing banks as intermediaries in financial transactions could result in the loss of fee income, as well as the loss of customer deposits and income generated from those deposits. Unauthorized disclosure of sensitive or confidential client or customer information, whether through cyber attacks, breach of computer systems or other means Our products, services and systems are accessed through critical company or third-party operations. This involves the storage, processing and transmission of sensitive data, including proprietary or confidential data, regulated data, and personal information of employees and customers. Successful breaches, employee wrongdoing, or human or technological error could result in unauthorized access to, disclosure, modification, misuse, loss, or destruction of company, customer, or other third party data or systems. Examples include theft of sensitive, regulated, or confidential data including personal information; loss of access to critical data or systems through ransomware, destructive attacks or other means; and business delays, service or system disruptions or denials of service. Cybersecurity incidents have increased in number and severity and it is expected that these trends will continue. Should we, or third parties we do business with, fall victim to successful cyber attacks or experience other cybersecurity incidents, including the loss of personally identifiable customer or other sensitive data, the result could severely damage our reputation, expose us to the risks of litigation and liability, disrupt our operations and increase cybersecurity or other insurance premiums. 8 Table of Contents We have cybersecurity insurance, in the event a cybersecurity attack were to occur, covering expenses related to notification, credit monitoring, investigation, crisis management, public relations, and legal advice. In addition, we maintain insurance to cover restoration of data, certain physical damage or third-party injuries caused by potential cybersecurity incidents. However, damage and claims arising from such incidents may not be covered or may exceed the amount of any insurance available. Insurance policies are reviewed annually in detail. A strong reputation is vital and requires utmost protection. An operating incident, significant cybersecurity disruption, or other adverse events may have a negative impact on our reputation which could make it more difficult for us to compete successfully for new opportunities, obtain necessary regulatory approvals, or severely reduce consumer demand for our products. Our estimates and assumptions may be incorrect Our consolidated financial statements conform with GAAP, which require us to make estimates and assumptions that affect the amounts reported in the consolidated financial statements. Estimates are based on information available to us at the time the estimates are made. Actual results could differ from estimates. For further discussion regarding significant accounting estimates, see “Note 1 – Nature of Operations and Summary of Significant Accounting Policies” of “Notes to Consolidated Financial Statements” in Item 8. Financial Statements and Supplementary Data. Disruption of infrastructure Our operations depend upon our technological and physical infrastructure, including our equipment and facilities. Extended disruption of our vital infrastructure by fire, power loss, natural disaster, telecommunications failure, computer hacking and viruses, or other events outside of our control, could have a significant impact on our operations. We have developed and tested disaster recovery plans for all significant aspects of our operations. Anti-takeover provisions Our articles of incorporation include anti-takeover provisions that require a two-thirds majority vote of our shareholders to approve a sale of the Corporation. Additionally, changes to our articles of incorporation must be approved by a two-thirds majority vote of our shareholders. These provisions may make our common stock less attractive to potential shareholders. Item 1B. Unresolved Staff Comments. None. Item 2. Properties. Our executive offices are located at 401 North Main Street in Mount Pleasant, Michigan. In addition to this location, we own 29 branches, two operations centers, our previous main office building and vacant land. We also lease property in Saginaw, Michigan which serves as a full-service branch. Our facilities' current, planned, and best use is for conducting our current activities, with the exception of our previous main office location which is vacant. We continually monitor and assess the need for expansion and/or improvement of all facilities. In our opinion, each facility has sufficient capacity and is in good condition. Item 3. Legal Proceedings. We are not involved in any material legal proceedings. While we are involved in ordinary, routine litigation incidental to our business, no such routine proceedings are expected to result in any material adverse effect on our consolidated operations, earnings, financial condition, or cash flows. Item 4. Mine Safety Disclosures. Not applicable. 9 Table of Contents Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities.

Management's Discussion and Analysis of Financial Condition and Results of Operations. ISABELLA BANK CORPORATION FINANCIAL REVIEW (Dollars in thousands except per share amounts) The following is management’s discussion and analysis of our financial condition and results of operations. This discussion and analysis is intended to provide a better understanding of the consolidated financial statements and statistical data included elsewhere in this Annual Report on Form 10-K. Executive Summary We reported net income of $10,885 and earnings per common share of $1.37 for the year ended December 31, 2020. Net income and earnings per common share for the year ended December 31, 2019 were $13,024 and $1.65, respectively. A decline in the interest rate environment was a large driver of a $3,134 decrease in interest income for 2020 when compared to 2019. Interest expense on deposits and borrowings decreased $4,036 for the year ended December 31, 2020 when compared to the same period in 2019 primarily due to reduced interest rates and reduced reliance on higher-cost borrowings. Net interest income increased by $902 for the year ended December 31, 2020 in comparison to the prior year. The provision for loan losses increased by $1,635 in 2020 when compared to 2019 as the result of increased economic and environmental risk factors, predominantly driven by COVID-19. Noninterest income for the year ended December 31, 2020 increased $6,384 when compared to 2019 mainly as a result of net gain on sold mortgage loans and the redemption of corporate owned life insurance policies. Our joint venture investment in Corporate Settlement Solutions, LLC (“CSS”) also contributed to the variance in noninterest income. We sold our membership interest in CSS during the fourth quarter of 2020, which resulted in a $394 reduction in income. During the fourth quarter of 2019, we recorded a reduction of $3,566 in our joint venture investment in CSS due to CSS' recorded impairment of intangible assets. Noninterest expenses for the year ended December 31, 2020 increased $8,183 when compared to 2019, which can be attributed to a $7,643 cost to extinguish $100,000 of FHLB advances. As a result of this debt extinguishment, future interest expense and net yields are expected to be impacted favorably. As of December 31, 2020, total assets and assets under management were $1,957,378 and $2,702,722, respectively. Assets under management include loans sold and serviced of $301,377 and investment and trust assets managed by Isabella Wealth of $443,967, in addition to assets on our consolidated balance sheet. In the first half of 2020, the Bank’s investment and trust services business was re-engineered and rebranded as Isabella Wealth to enhance the client experience, build scalability, and expand market awareness. Loans outstanding as of December 31, 2020 totaled $1,238,311. During 2020, gross loans increased $51,741 which was largely the result of SBA PPP loans in the commercial loan portfolio. Our securities portfolio declined $90,611 since December 31, 2019, predominantly as a result of increased monthly prepayments and payoffs of AFS securities. Due to the flat yield curve that has existed for the last few years, the opportunity to identify new investment securities for purchase at an acceptable yield has been minimal. Based on strategic objectives, we utilized this available cash flow to reduce higher-cost funding sources and other borrowings as they matured. Total deposits increased $252,466 during the year, driven by growth in demand and savings deposits, and totaled $1,566,317 as of December 31, 2020. All regulatory capital ratios for the Bank exceeded the minimum thresholds to be considered a “well capitalized” institution. Our net yield on interest earning assets (FTE) was 2.96% for 2020 which declined from 3.07% in 2019. Management implemented strategic programs focused on improving our net yield on interest earning assets, which includes enhanced pricing related to loans and a reduced reliance on higher-cost borrowed funds and brokered deposits as funding sources. While these efforts have helped, the current interest rate environment has had a negative impact on the yield of interest earning assets and future improvements may be gradual. We are committed to increasing earnings and shareholder value through growth in our loan portfolio while maintaining strong underwriting standards, growth in our wealth management services, managing operating costs and increasing our presence within our geographical footprint. Recent Events and Legislation Restricted Stock Plan: On June 24, 2020, the Board of Directors adopted the RSP, an equity-based bonus plan. The RSP authorizes the issuance of unvested restricted stock to an eligible employee with a maximum award ranging from 25% to 40% of the employee’s annual salary, on a calendar year basis. Under the RSP, the Board of Directors may grant restricted stock awards to eligible employees on an annual basis based on the satisfactory achievement of performance targets and measures established by the Board of Directors. If these grant conditions are not satisfied, then the award of restricted shares will lapse or be adjusted appropriately, at the discretion of the Board of Directors. Restricted stock awards granted are not fully transferable or vested until certain conditions are met, as stated in the plan. In connection with the adoption of the RSP, the Isabella Bank Corporation Stock Award Incentive Plan was terminated. 14 Table of Contents Also on June 24, 2020, we made initial awards under the RSP to Isabella Bank's CEO, President, and CFO. As of December 31, 2020, certain targets specified in the award agreements pursuant to the RSP were achieved and therefore, we recognized compensation expense of $14 pursuant to the RSP. Additional disclosures about the RSP are included in “Note 13 – Benefit Plans” of “Notes to Consolidated Financial Statements” in Item 8. Financial Statements and Supplementary Data. Executive Cash Incentive Plan: Also on June 24, 2020, we amended and restated the Isabella Bank Corporation Employee Cash Incentive Plans to create two separate plans: one for non-executive employees and the other, the Isabella Bank Corporation Executive Cash Incentive Plan for executive employees. The executive plan provides separate potential payouts for Isabella Bank's CEO, President and CFO based on achievement of personal and corporate goals. The potential payouts under the plan range from 20% to 30% of the employee's annual salary. Impact of COVID-19: Unexpected and unprecedented changes have occurred during 2020 and into 2021 as the result of COVID-19. This aggressive and persistent virus causes a respiratory disease and can result in serious illness or death. The World Health Organization has declared the situation a global pandemic. The pandemic has created significant market volatility, economic uncertainty, and disruption to normal business operations around the world, with slowdowns and shutdowns affecting entire industries. The Michigan governor issued on March 23, 2020 a stay-at-home order, which limited gatherings and travel, and required those in select businesses who were not deemed essential to sustain or protect life to stay home. The Michigan stay-at-home order was in effect until early June. Additional executive and Michigan State Health Department orders have been put in place since June 2020. During the fourth quarter of 2020, certain restrictions were put in place on industries within our communities and continued through December 31, 2020. The orders, as the result of COVID-19, led to financial stress for many businesses and their employees throughout the communities we serve. The CARES Act, an unprecedented federal government support program, was enacted on March 27, 2020 in response to the COVID-19 pandemic. It is a $2 trillion stimulus package intended to provide financial relief across the country. The CARES Act included the PPP, which enabled businesses to obtain a forgivable SBA loan to meet payroll, rent, utility, and mortgage interest obligations for the 24-week period following the loan origination, and re-open quickly once the public health crisis ends. The first applications for PPP funds, with a term of two years, were accepted April 3, 2020. During 2020, we were privileged to have facilitated more than 950 SBA PPP loans for a total of $99,459 and we are pleased to have the opportunity to provide additional funding in 2021 under an additional government stimulus program. Bank regulators issued an interim rule that neutralizes the regulatory capital effects by allowing a zero percent risk weight, for capital purposes, to loans originated under the PPP. The capital rule was issued April 9, 2020, with an immediate effective date. During 2020, many of our customers expressed their general concern about the uncertain economic conditions, but it is still premature to reasonably predict the magnitude of the impact. One measure we took to assist our customers included reduced service charges and fees on deposit accounts. Since the COVID-19 pandemic led to an increase in the need for electronic services and products, we elected to temporarily waive certain charges and fees, and permanently remove some charges and fees, to ease the financial stress on our customers. Other measures we have taken to assist our customers include loan programs that provide short-term payment relief. Under these programs, borrowers whose loans were in good standing as of March 1, 2020 could elect to defer full or partial payments for a period not to exceed 180 days. Loan payment deferrals totaled $306,103, or 23.8% of gross loans, as of June 30, 2020. As of September 30, 2020, active loan payment deferrals declined to $103,858, or 8.0% of gross loans, as the majority of borrowers granted loan payment deferrals had reverted back to contractual payments. As of December 31, 2020, active loan payment deferrals declined even further and totaled $6,048, or 0.5% of gross loans. Bank regulators issued a statement on March 22, 2020, and a revised statement on April 7, 2020, which provided confirmation that short-term loan modifications made on a good faith basis in response to COVID-19 to borrowers with a current payment status are not categorized as TDRs. Pursuant to this guidance, borrowers granted a short-term loan modification meeting this criteria were not categorized as TDR as of December 31, 2020. These programs, along with the SBA PPP, could mask or delay the detection or reporting of deterioration in credit quality indicators. The extent to which COVID-19 impacts our business will depend on future developments, which are highly uncertain and cannot be predicted with any accuracy. Future developments include new information which may emerge concerning the severity of COVID-19 and the actions to contain the coronavirus or treat its impact, among others. We expect the significance of the pandemic, including the extent of its effect on our financial and operational results, to be dictated by, among other factors, its duration, the success of efforts to contain it and the impact of actions taken in response, including the development and distribution of effective vaccines. Uncertainty created by the pandemic is pervasive, and has impacted our operations, customers, and various areas of risk. With the uncertainty created by COVID-19, it's challenging to determine the full impact 15 Table of Contents on our ongoing financial and operational results. We continue to closely monitor external events and are in continual discussion with our customers to assess, prepare and respond to conditions as they evolve. Reclassifications Certain amounts reported in management's discussion and analysis of financial condition and results of operations for 2019 and 2018 have been reclassified to conform with the 2020 presentation. Other assets and other liabilities on the consolidated balance sheets were decreased by $1,555 as of December 31, 2019 to reclassify pension liabilities. This resulted in a $1,555 decrease in total assets and total liabilities as of December 31, 2019. All other balances and ratios were not materially impacted. Subsequent Events We evaluated subsequent events after December 31, 2020 through the date our consolidated financial statements were issued for potential recognition and disclosure. No subsequent events require financial statement recognition or disclosure between December 31, 2020 and the date our consolidated financial statements were issued. Other We have not received, nor are aware of, any notices of regulatory actions as of March 9, 2021. CRITICAL ACCOUNTING POLICIES Our significant accounting policies are set forth in “Note 1 – Nature of Operations and Summary of Significant Accounting Policies” of “Notes to Consolidated Financial Statements” in Item 8. Financial Statements and Supplementary Data. Of these significant accounting policies, we consider our policies regarding the ALLL, acquisition intangibles and goodwill, and the determination of the fair value and assessment of OTTI of investment securities to be our most critical accounting policies. The ALLL requires our most subjective and complex judgment. Changes in economic conditions and other external factors can have a significant impact on the ALLL and, therefore, the provision for loan losses and results of operations. We have developed policies and procedures for assessing the appropriateness of the ALLL, recognizing that this process requires a number of assumptions and estimates with respect to our loan portfolio. Our assessments may be impacted in future periods by changes in economic conditions, and the discovery of information with respect to borrowers which is not known to us at the time of the issuance of the consolidated financial statements. For additional discussion concerning our ALLL and related matters, see “Allowance for Loan and Lease Losses” and “Note 4 – Loans and ALLL” of “Notes to Consolidated Financial Statements” in Item 8. Financial Statements and Supplementary Data. U.S. generally accepted accounting principles require that we determine the fair value of the assets and liabilities of an acquired entity, and record the fair value on the date of acquisition. We employ a variety of measures in the determination of the fair value, including the use of discounted cash flow analysis, market appraisals, and projected future revenue streams. For certain items that we believe we have the appropriate expertise to determine the fair value, we may choose to use our own calculations of the value. In other cases, where the value is not easily determined, we consult with independent experts to determine the fair value of the identified asset or liability. Once valuations have been determined, the net difference between the price paid for the acquired entity and the net value of assets acquired on our balance sheet, including identifiable intangibles, is recorded as goodwill. Acquisition intangibles and goodwill are qualitatively evaluated to determine if it is more likely than not that the carrying balance is impaired on at least an annual basis. During the fourth quarter of 2020, we engaged a third-party valuation firm to perform a quantitative analysis of goodwill as of December 31, 2020. In determining the fair value of the Bank and Isabella Bank Corporation, the third-party firm assessed general economic conditions, industry and market considerations, the impact of recent events to financial performance, the market price of our common stock, and other relevant events. Based on the valuation prepared, it was determined that our estimated fair values of the Bank and Isabella Bank Corporation at December 31, 2020 were greater than our recorded book value and no impairment of goodwill was identified. The carrying amount of goodwill as of December 31, 2020 relied on assumptions and use of estimates pursuant to the valuations obtained. AFS securities are carried at fair value with changes in the fair value included as a component of other comprehensive income. Declines in the fair value of AFS securities below their cost that are other-than-temporary are reflected as realized losses in the consolidated statements of income. We evaluate AFS securities for indications of losses that are considered other-than-temporary, if any, on a regular basis. The market values for most AFS investment securities are typically obtained from outside sources and applied to individual securities within the portfolio. Municipal securities for which no readily determinable market values are available are priced using fair value curves which most closely match the securities' characteristics. 16 Table of Contents Average Balances, Interest Rates, and Net Interest Income The following schedules present the daily average amount outstanding for each major category of interest earning assets, non-earning assets, interest bearing liabilities, and noninterest bearing liabilities for the last three years. These schedules also present an analysis of interest income and interest expense for the periods indicated. All interest income is reported on a FTE basis using a federal income tax rate of 21%. Loans in nonaccrual status, for the purpose of the following computations, are included in the average loan balances. FRB and FHLB restricted equity holdings are included in other interest earning assets. 2020 Tax Equivalent Interest Average Balance 1,236,169 $ 229,468 140,665 4 142,717 1,749,023 54,102 5,214 5,189 — 1,026 65,531 (8,837) 24,987 25,846 118,195 1,909,214 Year Ended December 31 2019 Average Yield / Rate Average Balance Tax Equivalent Interest Average Yield / Rate Average Balance 2018 Tax Equivalent Interest Average Yield / Rate 4.38 % $ 2.27 % 3.69 % 0.06 % 0.72 % 3.75 % 1,162,210 $ 296,758 169,049 64 38,549 1,666,630 54,192 7,185 6,380 2 1,199 68,958 4.66 % $ 2.42 % 3.77 % 2.48 % 3.11 % 4.14 % 1,120,021 $ 341,095 191,281 4 28,255 1,680,656 49,229 8,294 7,115 — 1,062 65,700 4.40 % 2.43 % 3.72 % — % 3.76 % 3.91 % (8,256) 20,057 27,035 108,073 1,813,539 $ (8,094) 19,770 28,349 95,359 1,816,040 $ 262,188 $ 456,088 387,881 245,969 1,352,126 357 1,212 7,315 4,941 13,825 0.14 % $ 0.27 % 1.89 % 2.01 % 1.02 % 230,570 $ 388,821 429,745 304,888 1,354,024 305 2,572 8,731 6,253 17,861 0.13 % $ 0.66 % 2.03 % 2.05 % 1.32 % 229,411 $ 361,743 454,916 344,352 1,390,422 267 1,698 7,296 6,370 15,631 0.12 % 0.47 % 1.60 % 1.85 % 1.12 % $ $ $ INTEREST EARNING ASSETS (1) Loans Taxable investment securities Nontaxable investment securities Fed funds sold Other Total earning assets NONEARNING ASSETS Allowance for loan losses Cash and demand deposits due from banks Premises and equipment Accrued income and other assets Total assets INTEREST BEARING LIABILITIES Interest bearing demand deposits Savings deposits Time deposits Borrowed funds Total interest bearing liabilities NONINTEREST BEARING LIABILITIES Demand deposits Other Shareholders’ equity 320,820 15,613 220,655 Total liabilities and shareholders’ equity $ 1,909,214 237,675 13,337 208,503 224,777 7,597 193,244 $ 1,813,539 $ 1,816,040 Net interest income (FTE) $ 51,706 $ 51,097 $ 50,069 Net yield on interest earning assets (FTE) 2.96 % 3.07 % 2.98 % (1) Includes taxable AFS securities and equity securities Net interest income is the amount by which interest income on earning assets exceeds the interest expense on interest bearing liabilities. Net interest income is influenced by changes in the balance and mix of assets and liabilities, as well as market interest rates. We exert some control over these factors; however, FRB monetary policy and competition have a significant impact. For analytical purposes, net interest income is adjusted to an FTE basis by including the income tax savings from interest on tax exempt loans and nontaxable investment securities, thus making year to year comparisons more meaningful. The FTE adjustment is based on a federal income tax rate of 21%. 17 Table of Contents Volume and Rate Variance Analysis The following table sets forth the effect of volume and rate changes on interest income and expense for the periods indicated. For the purpose of this table, changes in interest due to volume and rate were determined as follows: Volume—change in volume multiplied by the previous period's FTE rate. Rate—change in the FTE rate multiplied by the previous period's volume. All interest income presented in the table below is reported on a FTE basis using a federal income tax rate of 21%. The change in interest due to both volume and rate has been allocated to volume and rate changes in proportion to the relationship of the absolute dollar amounts of the change in each. $ Changes in interest income Loans Taxable investment securities Nontaxable investment securities Fed Funds Sold Other Total changes in interest income Changes in interest expense Interest bearing demand deposits Savings deposits Time deposits Borrowed funds Total changes in interest expense Net change in interest margin (FTE) $ 2020 Compared to 2019 Increase (Decrease) Due to Rate Volume Net Volume 2019 Compared to 2018 Increase (Decrease) Due to Rate Net 3,341 $ (1,550) (1,050) (1) 1,301 2,041 43 385 (815) (1,186) (1,573) 3,614 $ (3,431) $ (421) (141) (1) (1,474) (5,468) 9 (1,745) (601) (126) (2,463) (3,005) $ (90) $ (1,971) (1,191) (2) (173) (3,427) 52 (1,360) (1,416) (1,312) (4,036) 609 $ 1,898 $ (1,074) (838) — 342 328 1 135 (422) (771) (1,057) 1,385 $ 3,065 $ (35) 103 2 (205) 2,930 37 739 1,857 654 3,287 (357) $ 4,963 (1,109) (735) 2 137 3,258 38 874 1,435 (117) 2,230 1,028 The flattening of the yield curve continues to place pressure on our net interest margin.

Loans represent our single largest concentration of risk. The ALLL is our estimation of incurred losses within the existing loan portfolio. We allocate the ALLL throughout the loan portfolio based on our assessment of the underlying risks associated within each loan segment. Our assessments include allocations based on specific impairment valuation allowances, historical charge- offs, internally assigned credit risk ratings, and past due and nonaccrual balances. A portion of the ALLL is not allocated to any one loan segment, but is instead a representation of other qualitative risks that reflect the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio. The following table summarizes our charge-offs, recoveries, provision for loan losses, and ALLL balances as of, and for the unaudited three month periods ended: Total charge-offs Total recoveries Net loan charge-offs (recoveries) Net loan charge-offs (recoveries) to average loans outstanding Provision for loan losses Provision for loan losses to average loans outstanding ALLL ALLL as a % of loans at end of period $ $ $ December 31 2020 September 30 2020 June 30 2020 March 31 2020 December 31 2019 $ $ $ 111 93 18 — % 256 0.02 % 9,744 0.79 % $ $ $ 46 159 (113) (0.01)% 516 0.04 % 9,506 0.73 % $ $ $ 66 141 (75) (0.01)% 105 0.01 % 8,877 0.69 % $ $ $ 158 128 30 — % 788 0.07 % 8,697 0.74 % 334 122 212 0.02 % (18) — % 7,939 0.67 % The following table summarizes our charge-off and recovery activity for the years ended December 31: 2020 2019 2018 2017 2016 $ 7,939 $ 8,375 $ 7,700 $ 7,400 $ 7,400 ALLL at beginning of period Charge-offs Commercial Agricultural Residential real estate Consumer Total charge-offs Recoveries Commercial Agricultural Residential real estate Consumer Total recoveries Provision for loan losses ALLL at end of period Net loan charge-offs (recoveries) Net loan charge-offs (recoveries) to average loans outstanding ALLL as a % of loans at end of period $ $ 7 24 28 322 381 149 39 136 197 521 1,665 9,744 (140) $ $ 143 240 99 466 948 123 3 189 167 482 30 7,939 466 $ $ 575 51 151 324 1,101 325 3 261 209 798 978 8,375 303 $ $ 263 2 200 306 771 449 4 206 159 818 253 7,700 (47) $ $ 57 — 574 285 916 445 95 287 224 1,051 (135) 7,400 (135) (0.01)% 0.79 % 0.04 % 0.67 % 0.03 % 0.74 % — % 0.71 % (0.01)% 0.73 % While we have experienced fluctuations in credit quality indicators in recent periods, credit quality remained strong at December 31, 2020. The COVID-19 pandemic led to some temporary and permanent closures of businesses throughout the communities in which we serve, which resulted in increased unemployment. We increased the ALLL during the year as a result of increased economic and environmental related risk factors, primarily driven by COVID-19. 19 Table of Contents The economic impact from the COVID-19 pandemic could pose significant credit risk due to the potential inability of consumer and commercial borrowers to make contractual payments. In late March 2020, we implemented payment programs for borrowers to alleviate the financial setback due to the temporary closure of businesses and lost wages. These programs, along with the SBA PPP, could mask or delay the detection and reporting of deterioration in credit quality indicators. We continue to monitor the economic impact from COVID-19 as it relates to credit risk to ensure the ALLL is appropriate. The following table illustrates the two main components of the ALLL as of: ALLL Individually evaluated for impairment Collectively evaluated for impairment Total ALLL to gross loans Individually evaluated for impairment Collectively evaluated for impairment Total December 31 2020 September 30 2020 June 30 2020 March 31 2020 December 31 2019 $ $ 911 8,833 9,744 $ $ 869 8,637 9,506 $ $ 950 7,927 8,877 $ $ 1,309 7,388 8,697 $ $ 0.07 % 0.72 % 0.79 % 0.07 % 0.66 % 0.73 % 0.07 % 0.62 % 0.69 % 0.11 % 0.63 % 0.74 % 1,114 6,825 7,939 0.09 % 0.58 % 0.67 % While we utilize our best judgment and information available, the ultimate adequacy of the ALLL is dependent upon a variety of factors beyond our control, including the performance of our borrowers, the economy, and changes in interest rates. We closely monitor overall credit quality indicators and our policies and procedures related to the analysis of the ALLL to ensure that the ALLL remains at an appropriate level. For further discussion of the allocation of the ALLL, see “Note 4 – Loans and ALLL” of “Notes to Consolidated Financial Statements” in Item 8. Financial Statements and Supplementary Data. Loans Past Due and Loans in Nonaccrual Status Fluctuations in past due and nonaccrual status loans can have a significant impact on the ALLL. To determine the potential impact, and corresponding estimated losses, we analyze our historical loss trends on loans past due greater than 30 days and nonaccrual status loans for indications of additional deterioration.

Financial Statements and Supplementary Data. 20 Table of Contents Troubled Debt Restructurings We have taken a proactive approach to modifying loans to assist borrowers who are willing to work with us, thus making them less likely to default, and to avoid foreclosure. This approach has permitted certain borrowers to develop a payment structure that will allow them to continue making payments in lieu of foreclosure. Modifications have been successful for us and our customers as very few of the modified loans have resulted in foreclosures. The majority of new modifications result in terms that satisfy our criteria for continued interest accrual. TDRs that have been placed in nonaccrual status may be placed back on accrual status after six months of continued performance and achievement of current payment status. We restructure debt with borrowers who due to financial difficulties are unable to service their debt under the original terms. We may extend the amortization period, reduce interest rates, allow temporary interest-only payment structures, forgive principal, forgive interest, or grant a combination of these modifications. Typically, the modifications are for a period of three years or less. There were no TDRs that were government sponsored as of December 31, 2020 or December 31, 2019. Losses associated with TDRs, if any, are included in the estimation of the ALLL during the quarter in which a loan is identified as a TDR, and we review the analysis of the ALLL estimation each reporting period thereafter to ensure its continued appropriateness. The following table provides a roll-forward of TDRs for the years ended December 31, 2019 and 2020: Accruing Interest Nonaccrual Total Number of Loans Balance Number of Loans Balance Number of Loans Balance January 1, 2019 New modifications Principal advances (payments) Loans paid off Partial charge-offs Transfers to OREO Transfers to accrual status Transfers to nonaccrual status December 31, 2019 New modifications Principal advances (payments) Loans paid off Partial charge-offs Transfers to OREO Transfers to accrual status Transfers to nonaccrual status December 31, 2020 28 — — (15) — (1) (9) 6 9 3 — (2) — (2) (1) — 7 $ $ 3,551 — (382) (1,596) (65) (48) (1,219) 3,302 3,543 645 (148) (850) — (356) (104) — 2,730 161 $ 11 — (40) — (1) — — 131 18 — (32) — (2) — — 115 $ 26,951 4,491 (1,677) (4,915) (65) (48) — — 24,737 8,554 (1,838) (6,167) — (356) — — 24,930 133 $ 11 — (25) — — 9 (6) 122 15 — (30) — — 1 — 108 $ 23,400 4,491 (1,295) (3,319) — — 1,219 (3,302) 21,194 7,909 (1,690) (5,317) — — 104 — 22,200 21 Table of Contents The following table summarizes our TDRs as of December 31: Current Past due 30-59 days Past due 60-89 days Past due 90 days or more Total Accruing Interest $ $ 22,017 $ 183 — — 22,200 $ 2020 Nonaccrual 2,421 $ — — 309 2,730 $ Total 24,438 $ 183 — 309 24,930 $ 2019 2018 Accruing Interest Nonaccrual Total Accruing Interest Nonaccrual Total 20,847 $ 346 1 — 21,194 $ 507 $ — — 3,036 3,543 $ 21,354 $ 346 1 3,036 24,737 $ 21,794 $ 899 707 — 23,400 $ 2,673 $ — — 878 3,551 $ 24,467 899 707 878 26,951 Current Past due 30-59 days Past due 60-89 days Past due 90 days or more Total Accruing Interest $ $ 21,234 $ 1,778 219 53 23,284 $ 2017 2016 Nonaccrual Total Accruing Interest Nonaccrual Total — $ 805 708 1,400 2,913 $ 21,234 $ 2,583 927 1,453 26,197 $ 17,557 $ 2,898 138 — 20,593 $ 559 230 — — 789 $ $ 18,116 3,128 138 — 21,382 Additional disclosures about TDRs are included in “Note 4 – Loans and ALLL” of “Notes to Consolidated Financial Statements” in Item 8.

Upon transferring a loan to nonaccrual status, we perform an evaluation to determine the net realizable value of the underlying collateral. This evaluation is used to help determine if a charge-off is necessary. Consumer loans are typically charged-off no later than 180 days past due. Loans may be placed back on accrual status after six months of continued performance and achievement of current payment status. While the level of nonperforming loans has fluctuated in recent periods, it remains low in comparison to peer banks.

While we do not anticipate significant changes to our ATM and debit card fee structure, we do expect that fee income will continue to increase in 2021 as the usage of ATM and debit cards continues to increase. Service charges and fees on deposit accounts declined in 2020 as a result of waived fees. In response to COVID-19, which has led to an increase in the need for electronic services and products, we elected to temporarily waive certain charges and fees, and permanently remove some charges and fees, to ease the financial stress of our customers. As such, we expect service charges and fees in 2021 to approximate 2020 levels. OMSR income results are driven, in part, by changes in offering rates on residential mortgage loans, anticipated prepayments in the servicing-retained portfolio, and the volume of loans within the servicing-retained portfolio. Increased prepayment speeds, as a result of a decline in interest rates during the first quarter of 2020, were the primary driver of the losses recognized during the first half of 2020. During the second half of 2020, the volume of loans serviced increased which resulted in an increase in the value of the servicing rights. OMSR income during 2021 may continue to experience fluctuations and could vary from 2020 levels. Net gain on sale of mortgage loans fluctuates as the result of a change in the amount of loans sold and pricing. The amount of loans sold is driven by customer demand and balance sheet management strategies. We experienced a significant increase in loan demand during 2020 which led to an increase in the number and dollar amount of loans sold during the year. As such, net gain on sale of mortgage loans increased significantly. As demand is expected to slow during 2021, net gain on sale of mortgage loans is not expected to exceed 2020 levels. The decrease in wealth management fees, primarily during the first quarter of 2020, was driven by a decline in the stock market causing the value of investment assets under management to decrease. While strategic additions in staffing have already led to new business within Isabella Wealth, wealth management fees during 2021 may not exceed 2020 levels due to the uncertainty in the stock market as a result of COVID-19. We recognized income during 2020 due to the redemption of corporate owned life insurance policies in connection with the passing of three retired bank employees. 24 Table of Contents We sold our membership interest in our joint venture investment in CSS during the fourth quarter of 2020, which resulted in a $394 reduction in income. As a result of a valuation during the fourth quarter of 2019, CSS recognized a $7,133 impairment related to intangible assets as of December 31, 2019. Since we accounted for our investment in CSS under the equity method of accounting, we reduced our investment in CSS by $3,566 during the fourth quarter of 2019. The fluctuations in all other income are spread throughout various categories, none of which are individually significant. Significant noninterest expense balances are highlighted in the following table for the years ended December 31: Compensation and benefits Losses on extinguishment of debt Furniture and equipment Occupancy Other Audit, consulting, and legal fees ATM and debit card fees Marketing costs Loan underwriting fees Donations and community relations Director fees FDIC insurance premiums All other Total other Total noninterest expenses $ $ 2020 23,772 $ 7,643 5,787 3,557 2019 23,205 $ — 5,866 3,418 1,836 1,441 877 825 723 695 612 3,465 10,474 51,233 $ 1,884 1,210 762 905 1,026 788 211 3,775 10,561 43,050 $ Change Change $ % 2018 $ % 567 7,643 (79) 139 (48) 231 115 (80) (303) (93) 401 (310) (87) 8,183 2.44 % $ N/M (1.35) % 4.07 % (2.55) % 19.09 % 15.09 % (8.84) % (29.53) % (11.80) % 190.05 % (8.21) % (0.82) % 19.01 % $ 22,609 $ — 6,055 3,263 2,222 1,036 596 1,016 710 858 726 3,761 10,925 42,852 $ 596 — (189) 155 (338) 174 166 (111) 316 (70) (515) 14 (364) 198 2.64 % — % (3.12) % 4.75 % (15.21) % 16.80 % 27.85 % (10.93) % 44.51 % (8.16) % (70.94) % 0.37 % (3.33) % 0.46 % Significant changes in noninterest expenses are detailed below: During the fourth quarter of 2020, we incurred expense of $7,643 as a result of the extinguishment of $100,000 of FHLB advances. Audit, consulting, and legal fees in 2018 included one-time charges related to income tax strategies. As a result, 2020 and 2019 expenses were less than 2018 expenses. We have experienced increased usage of ATM and debit cards which has resulted in increased income and also increased ATM and debit card expenses. Based on the anticipated continuation of increased ATM and debit card usage, we expect expenses to increase in 2021. Loan underwriting fees increased during the second half of 2018 and continued in the first quarter of 2019 as a result of new loan products, including first time home buyer and down payment assistance programs designed to generate residential mortgage growth. Loan underwriting fees in 2019 did not exceed 2018 levels based on the nature of products offered during 2019. Additionally, loan underwriting fees in 2020 did not exceed 2019 levels. Fees in 2021 are expected to approximate 2020 levels. Donations and community relations increased during 2019 as a result of initiatives designed to deepen and strengthen our relationship with the communities in which we operate and serve. In addition to providing monetary contributions, some of these initiatives include volunteering our time, which is not a component of donations and community relations costs. Government restrictions and temporary business closures related to COVID-19 impacted our ability to maintain their level of support in 2020. Donations and community relations is expected to approximate 2020 levels in 2021. As a result of an assessment credit of $440 received during the third quarter of 2019, FDIC insurance premiums declined in 2019 as compared to 2020 and 2018 expenses. FDIC insurance premiums in 2021 are expected to approximate 2020 levels. 25 Table of Contents All other expenses declined during 2020 primarily as a result of reduced employee education and travel expenses. Due to COVID-19, many events were cancelled or offered at no cost. While education and travel expenses in 2021 are expected to exceed 2020 levels, expenses are not expected to resume normal levels and as a result, total all other expenses are not expected to resume normal levels. The fluctuations in all other expenses are spread throughout various categories, none of which are individually significant. Analysis of Changes in Financial Condition The following table shows the composition and changes in our balance sheet as of December 31: ASSETS Cash and cash equivalents AFS securities Amortized cost of AFS securities Unrealized gains (losses) on AFS securities AFS securities Mortgage loans AFS Loans Gross loans Less allowance for loan and lease losses Net loans Premises and equipment Corporate owned life insurance policies Accrued interest receivable Equity securities without readily determinable fair values Goodwill and other intangible assets Other assets TOTAL ASSETS LIABILITIES AND SHAREHOLDERS’ EQUITY Liabilities Deposits Borrowed funds Accrued interest payable and other liabilities Total liabilities Shareholders’ equity 2020 2019 $ % Change $ 246,640 $ 60,572 $ 186,068 N/M 325,966 13,262 339,228 2,741 1,238,311 9,744 1,228,567 25,140 28,292 6,882 17,383 48,331 14,174 1,957,378 $ 423,980 5,859 429,839 904 1,186,570 7,939 1,178,631 26,242 28,455 6,501 21,629 48,379 11,491 1,812,643 $ (98,014) 7,403 (90,611) 1,837 51,741 1,805 49,936 (1,102) (163) 381 (4,246) (48) 2,683 144,735 1,566,317 $ 158,747 13,726 1,738,790 218,588 1,313,851 $ 275,999 12,611 1,602,461 210,182 252,466 (117,252) 1,115 136,329 8,406 $ $ (23.12) % 126.35 % (21.08) % N/M 4.36 % 22.74 % 4.24 % (4.20) % (0.57) % 5.86 % (19.63) % (0.10) % 23.35 % 7.98 % 19.22 % (42.48) % 8.84 % 8.51 % 4.00 % 7.98 % TOTAL LIABILITIES AND SHAREHOLDERS’ EQUITY $ 1,957,378 $ 1,812,643 $ 144,735 A discussion of changes in balance sheet amounts by major categories follows: Cash and cash equivalents Included in cash and cash equivalents are funds held with the FRB which fluctuate from period to period. Cash levels increased significantly during 2020 as a result of increased monthly prepayments and payoffs of AFS securities, funding from the SBA for PPP loan forgiveness, and an increase in customer deposits. During 2020, excess funds were used to pay maturing long-term borrowings, extinguish long-term borrowings, and pay other short-term liabilities. Payments for maturing borrowings is expected to continue in 2021. 26 Table of Contents AFS securities The primary objective of our investing activities is to provide for safety of the principal invested. Secondary considerations include providing earnings and liquidity while managing our overall exposure to changes in interest rates. Over the last two years, the flat yield curve encouraged the use of excess funds to reduce higher-cost borrowings as opposed to investing in AFS securities. However, based on balance sheet strategies, excess funds above what is required to retire higher- cost funding sources may prudently be deployed to purchase of AFS securities in future periods. The following is a schedule of the carrying value of AFS securities as of December 31: Government sponsored enterprises States and political subdivisions Auction rate money market preferred Mortgage-backed securities Collateralized mortgage obligations Corporate Total 2020 2019 2018 $ $ — $ 143,656 3,237 88,652 101,983 1,700 339,228 $ — $ 169,752 3,119 140,204 116,764 — 429,839 $ 170 190,866 2,554 184,484 116,760 — 494,834 Excluding those holdings in government sponsored enterprises and municipalities within the State of Michigan, there were no investments in securities of any one issuer that exceeded 10% of shareholders’ equity during 2020, 2019, and 2018. We have a policy prohibiting investments in securities that we deem unsuitable due to their inherent credit or market risks. Prohibited investments include stripped mortgage-backed securities, zero coupon bonds, nongovernment agency asset- backed securities, and structured notes. Our holdings in mortgage-backed securities and collateralized mortgage obligations include only government agencies and government sponsored agencies as we hold no investments in private label mortgage-backed securities or collateralized mortgage obligations. The following is a schedule of maturities of AFS securities and their weighted average yields as of December 31, 2020. Weighted average yields have been computed on an FTE basis using a tax rate of 21%. Our auction rate money market preferred investments are long-term floating rate instruments. The issuers of auction rate securities generally have the right to redeem or refinance the debt. Because of their lack of contractual maturities, auction rate money market preferred stocks are not reported by a specific maturity group. Mortgage-backed securities and collateralized mortgage obligations are not reported by a specific maturity group due to their variable monthly payments. Expected maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations.

The proper management of credit and market risk inherent in the loan portfolio is critical to our financial stability. To control these risks, we have adopted strict underwriting standards, lending limits to a single borrower, loan to collateral value limits, and a defined market area. We also monitor and limit loan concentrations to specific industries. We have no foreign loans and there were no concentrations greater than 10% of total loans that are not disclosed as a separate category in the following table. The following table presents the composition of the loan portfolio for the years ended December 31: Commercial Agricultural Residential real estate Consumer Total 2020 2019 2018 2017 $ $ 756,686 $ 100,461 307,543 73,621 1,238,311 $ 700,941 $ 116,920 298,569 70,140 1,186,570 $ 659,529 $ 127,161 275,343 66,674 1,128,707 $ 634,759 $ 128,269 272,368 56,123 1,091,519 $ 2016 575,664 126,492 266,050 42,409 1,010,615 The following table presents the change in the loan portfolio categories for the years ended December 31: Commercial Agricultural Residential real estate Consumer Total 2020 2019 2018 $ Change % Change $ Change % Change $ Change % Change $ $ 55,745 (16,459) 8,974 3,481 51,741 7.95 % $ (14.08) % 3.01 % 4.96 % 4.36 % $ 41,412 (10,241) 23,226 3,466 57,863 6.28 % $ (8.05) % 8.44 % 5.20 % 5.13 % $ 24,770 (1,108) 2,975 10,551 37,188 3.90 % (0.86) % 1.09 % 18.80 % 3.41 % Loan demand has been negatively impacted by the pandemic and competition for new commercial loan opportunities continues to be strong. Growth in the commercial loan portfolio during 2020 was driven by SBA PPP loans. While we expect loan forgiveness on the remaining SBA PPP loans during 2021, we are still expecting overall growth during 2021 within the commercial portfolio as we continue to provide attractive and competitive loan products. Agricultural loans continued to decline in 2020 due to the competitive environment. Residential real estate and consumer loans have experienced growth over the last year and continued growth is expected in 2021. Equity securities without readily determinable fair values Included in equity securities without readily determinable fair values are restricted securities, which are carried at cost, and our joint venture investment in CSS accounted for under the equity method of accounting. We sold our membership interest in CSS during the fourth quarter of 2020, which reduced equity securities without readily determinable fair values $4,246 when compared to December 31, 2019. For more information related to this investment, refer to “Note 1 – Nature of Operations and Summary of Significant Accounting Policies”, “Note 6 – Investment in Joint Venture”, and “Note 18 – Fair Value” of “Notes to Consolidated Financial Statements” in Item 8. Financial Statements and Supplementary Data. Goodwill and other intangible assets Goodwill represents the excess of the amounts paid to acquire subsidiaries over the fair value of their net assets at the date of acquisition. The majority of the recorded goodwill is related to acquisitions of other banks, which were subsequently merged into Isabella Bank. If it is determined that the goodwill is impaired, a write-down of goodwill by the amount of the impairment would be required. The decline in economic conditions, as a result of the COVID-19 pandemic and other factors, led to a significant decline in the stock market causing the value of investments, including our stock, to decline. Our stock price was negatively impacted in March 2020, which continued during most of 2020. Since the price of our stock increased but had not fully recovered through the fourth quarter, we decided to engage a reputable, third-party valuation firm to perform a quantitative analysis of goodwill as of December 31, 2020. In determining the fair value of the Bank and Isabella Bank Corporation, the third-party firm assessed general economic conditions, industry and market considerations, the impact of recent events to financial performance, the market price of our common stock, and other relevant events. Based on the valuation prepared, it was determined that our 28 Table of Contents estimated fair values of the Bank and Isabella Bank Corporation at December 31, 2020 were greater than our recorded book value and no impairment of goodwill was identified. Furthermore, management noted that despite the decline of the market capitalization as a result of the COVID-19 pandemic, our financial performance remained positive. This is evidenced by our financial results, strong credit quality indicators, increased liquidity position, as well as the strong capital position. Finally, by the end of the fourth quarter, our stock price had increased to levels consistent with prices prior to the second quarter of 2020. Based on these factors and the results of the independent quantitative analysis of goodwill, management concluded that it was more likely than not that there was no goodwill impairment as of December 31, 2020. Other assets Other assets consist primarily of prepaid expenses, OMSR, receivables, and net deferred tax assets. As a result of the sale in our joint venture investment in CSS, we recorded a $3,227 receivable related to this transaction. For more information related to estimates and deferred taxes, refer to “Note 1 – Nature of Operations and Summary of Significant Accounting Policies” and “Note 16 – Federal Income Taxes” of “Notes to Consolidated Financial Statements” in Item 8. Financial Statements and Supplementary Data. Deposits Deposits are our primary source of funding. The following table presents the composition of the deposit portfolio as of December 31: Noninterest bearing demand deposits Interest bearing demand deposits Savings deposits Certificates of deposit Brokered certificates of deposit Internet certificates of deposit Total 2020 2019 2018 $ $ 375,395 $ 302,444 505,497 358,165 14,029 10,787 1,566,317 $ 249,152 $ 229,865 427,215 365,049 27,458 15,112 1,313,851 $ 236,534 235,287 387,252 358,127 62,148 13,345 1,292,693 The following table presents the change in the deposit categories for the years ended December 31: Noninterest bearing demand deposits Interest bearing demand deposits Savings deposits Certificates of deposit Brokered certificates of deposit Internet certificates of deposit Total 2020 2019 $ Change % Change $ Change % Change $ $ 126,243 72,579 78,282 (6,884) (13,429) (4,325) 252,466 50.67 % $ 31.57 % 18.32 % (1.89) % (48.91) % (28.62) % 19.22 % $ 12,618 (5,422) 39,963 6,922 (34,690) 1,767 21,158 5.33 % (2.30) % 10.32 % 1.93 % (55.82) % 13.24 % 1.64 % Total deposits have increased over the past 12 months with significant growth in non-contractual deposits, such as demand and savings deposits. This trend is anticipated to continue during 2021 as the financial markets continue to exhibit significant signs of instability. Additionally, government stimulus programs have driven growth in deposits. We experienced a decline in certificates of deposit over the past year as a result of the low interest rate environment. Brokered certificates of deposit offer another source of funding and may fluctuate from period to period based on our funding needs, including changes in assets such as loans and investments. During 2019 and 2020, we used excess funds to reduce higher-cost deposits, such as brokered certificates of deposit. This trend is expected to continue into 2021. 29 Table of Contents The remaining maturity of certificates of deposit of $250 or more as of December 31, 2020 was as follows: Maturity Within 3 months Within 3 to 6 months Within 6 to 12 months Over 12 months Total Borrowed Funds $ $ 43,687 6,257 28,064 29,184 107,192 Borrowed funds include FHLB advances, securities sold under agreements to repurchase, and federal funds purchased. The balance of borrowed funds fluctuates from period to period based on our funding needs that arise from changes in loans, investments, and deposits. To provide balance sheet growth, we may utilize borrowings and brokered deposits to fund earning assets. The following table presents borrowed funds balances for the years ended December 31: FHLB advances Securities sold under agreements to repurchase without stated maturity dates Total 2020 2019 2018 $ $ 90,000 $ 68,747 158,747 $ 245,000 $ 30,999 275,999 $ 300,000 40,299 340,299 During the fourth quarter of 2020, we elected to extinguish $100,000 of FHLB advances based on our level of cash reserves and strategic initiatives. Due to a significant increase in deposit accounts during the fourth quarter of 2020, our level of securities sold under agreements to repurchase increased as of December 31, 2020. We believe this to be a short-term increase and expect the balance of securities sold under agreements to repurchase to decline in the first half of 2021. We had no fed funds purchased for the years ended December 31, 2020, 2019, or 2018. For additional disclosure related to borrowed funds, see “Note 9 – Borrowed Funds” of “Notes to Consolidated Financial Statements” in Item 8. Financial Statements and Supplementary Data. Accrued interest payable and other liabilities Included in accrued interest payable and other liabilities are obligations related to our defined benefit pension plan and other employee benefits. For more information on the defined benefit pension plan and other employee benefits, see “Note 13 – Benefit Plans” of “Notes to Consolidated Financial Statements” in Item 8. Financial Statements and Supplementary Data. Contractual Obligations and Loan Commitments We have various financial obligations, including contractual obligations and commitments related to deposits and borrowings, which may require future cash payments. We also have loan related commitments that may impact liquidity. The commitments include unused lines of credit, commercial and standby letters of credit, and commitments to grant loans. These commitments to grant loans include residential mortgage loans with the majority committed to be sold to the secondary market. Many of these commitments historically have expired without being drawn upon and do not necessarily represent our future cash requirements. For additional disclosure related to Contractual Obligations and Loan Commitments, see “Note 10 – Off-Balance-Sheet Activities, Commitments and Other Matters” of “Notes to Consolidated Financial Statements” in Item 8. Financial Statements and Supplementary Data. 30 Table of Contents Capital Capital consists solely of common stock, retained earnings, and accumulated other comprehensive income (loss). We are authorized to raise capital through dividend reinvestment, employee and director stock purchases, and shareholder stock purchases. Pursuant to these authorizations, we issued 231,393 shares or $4,185 of common stock during 2020, and 209,583 shares or $4,876 of common stock in 2019. We offer the Directors Plan in which participants purchase stock units through deferred fees, in lieu of cash payments. Pursuant to this plan, we increased shareholders’ equity by $413 and $523 during 2020 and 2019, respectively. We also grant restricted stock awards pursuant to the RSP, effective June 24, 2020. Pursuant to this plan, we increased shareholders’ equity by $14 during 2020. We have a publicly announced common stock repurchase plan. Pursuant to this plan, we repurchased 144,950 shares or $2,702 of common stock during 2020 and 169,748 shares or $4,003 during 2019. As of December 31, 2020, we were authorized to repurchase up to an additional 102,956 shares of common stock. The FRB has established minimum risk-based capital guidelines. Pursuant to these guidelines, a framework has been established that assigns risk weights to each category of on and off-balance-sheet items to arrive at risk adjusted total assets. Regulatory capital is divided by the risk adjusted assets with the resulting ratio compared to the minimum standard to determine whether a corporation has adequate capital. The common equity tier 1 capital ratio has a minimum requirement of 4.50%. The minimum standard for primary, or Tier 1 capital is 6.00% and the minimum standard for total capital is 8.00%. The minimum requirements presented below include the minimum required capital levels based on the Basel III Capital Rules. Capital requirements to be considered well capitalized are based upon prompt corrective action regulations, as amended to reflect the changes under the Basel III Capital Rules. The following table sets forth these requirements and our ratios as of December 31: Common equity tier 1 capital Tier 1 capital Total capital Tier 1 leverage 2020 2019 Actual Minimum Required - BASEL III Required to be Considered Well Capitalized Actual Minimum Required - BASEL III Required to be Considered Well Capitalized 12.97 % 12.97 % 13.75 % 8.37 % 7.000 % 8.500 % 10.500 % 4.000 % 6.500 % 8.000 % 10.000 % 5.000 % 12.56 % 12.56 % 13.18 % 9.01 % 7.000 % 8.500 % 10.500 % 4.000 % 6.500 % 8.000 % 10.000 % 5.000 % There are no significant regulatory constraints placed on our capital. At December 31, 2020, the Bank exceeded minimum capital requirements. For further information regarding the Bank’s capital requirements, see “Note 11 – Minimum Regulatory Capital Requirements” of “Notes to Consolidated Financial Statements” in Item 8. Financial Statements and Supplementary Data. Fair Value We utilize fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. AFS securities, cash flow hedge derivative instruments and certain liabilities are recorded at fair value on a recurring basis. Additionally, from time to time, we may be required to record at fair value other assets on a nonrecurring basis, such as mortgage loans AFS, impaired loans, goodwill, foreclosed assets, OMSR, and certain other assets and liabilities. These nonrecurring fair value adjustments typically involve the application of lower of cost or market accounting or write downs of individual assets. For further information regarding fair value measurements, see “Note 1 – Nature of Operations and Summary of Significant Accounting Policies” and “Note 18 – Fair Value” of “Notes to Consolidated Financial Statements” in Item 8. Financial Statements and Supplementary Data. Liquidity Liquidity is monitored regularly by our ALCO, which consists of members of senior management. The committee reviews projected cash flows, key ratios, and liquidity available from both primary and secondary sources. Our primary sources of liquidity are cash and cash equivalents and unencumbered AFS securities. These categories totaled $444,051 or 22.69% of assets as of December 31, 2020 as compared to $291,190 or 16.06% as of December 31, 2019. The increase in both the amount and percentage of primary liquidity is a direct result of an increase in market deposits and a 31 Table of Contents deliberate reduction in non-market funding which required collateralization. Liquidity is important for financial institutions because of their need to meet loan funding commitments, depositor withdrawal requests, and various other commitments including expansion of operations, investment opportunities, and payment of cash dividends. Based on these same factors, daily liquidity could vary significantly. Deposit accounts are our primary source of funds. Our secondary sources include the ability to borrow from the FHLB, from the FRB, and through various correspondent banks in the form of federal funds purchased and a line of credit. These funding methods typically carry a higher interest rate than traditional market deposit accounts. In recent periods, we have elected to use excess funds and proceeds from the sale of AFS securities to reduce borrowings and other higher-cost funding sources. Some borrowed funds, including FHLB advances, FRB Discount Window advances, and repurchase agreements, require us to pledge assets, typically in the form of AFS securities or loans, as collateral. As of December 31, 2020, we had available lines of credit of $214,625. Our stress testing of liquidity increased during 2020 and continues to evolve due to economic uncertainly as a result of COVID-19. Our liquidity position remained strong at the end of 2020 which is illustrated in the following table: Total cash and cash equivalents Available lines of credit Fed funds lines with correspondent banks FHLB borrowings FRB Discount Window Other lines of credit Total available lines of credit 1 Unencumbered lendable value of FRB collateral, estimated Total cash and liquidity (1) Includes estimated unencumbered lendable value of FHLB collateral of $115,000 The following table summarizes our sources and uses of cash for the years ended December 31: Net cash provided by (used in) operating activities Net cash provided by (used in) investing activities Net cash provided by (used in) financing activities Increase (decrease) in cash and cash equivalents Cash and cash equivalents January 1 Cash and cash equivalents December 31 Market Risk December 31 2020 $ 246,640 93,000 106,638 9,987 5,000 214,625 160,000 621,265 $ 2020 2019 $ Variance $ $ 21,997 $ 45,133 118,938 186,068 60,572 246,640 $ 23,303 $ 15,480 (51,682) (12,899) 73,471 60,572 $ (1,306) 29,653 170,620 198,967 (12,899) 186,068 Our primary market risks are interest rate risk and liquidity risk. IRR is the exposure of our net interest income to changes in interest rates. IRR results from the difference in the maturity or repricing frequency of a financial institution's interest earning assets and its interest bearing liabilities. Managing IRR is the fundamental method by which financial institutions earn income and create shareholder value. Excessive exposure to IRR could pose a significant risk to our earnings and capital. The FRB has adopted a policy requiring banks to effectively manage the various risks that can have a material impact on safety and soundness. The risks include credit, interest rate, liquidity, operational, and reputational. We have policies, procedures, and internal controls for measuring and managing these risks. Specifically, our Funds Management policy and procedures include defining acceptable types and terms of investments and funding sources, liquidity requirements, limits on investments in long-term assets, limiting the mismatch in repricing opportunities of assets and liabilities, and the frequency of measuring and reporting to our Board of Directors. The primary technique to measure IRR is simulation analysis. Simulation analysis forecasts the effects on the balance sheet structure and net interest income under a variety of scenarios that incorporate changes in interest rates, the shape of yield curves, interest rate relationships, loan prepayments, and funding sources. These forecasts are compared against net interest income projected in a stable interest rate environment. While many assets and liabilities reprice either at maturity or in 32 Table of Contents accordance with their contractual terms, several balance sheet components demonstrate characteristics that require an evaluation to more accurately reflect their repricing behavior. Key assumptions in the simulation analysis include prepayments on loans, probable calls of investment securities, changes in market conditions, loan volumes and loan pricing, deposit sensitivity, and customer preferences. These assumptions are inherently uncertain as they are subject to fluctuation and revision in a dynamic rate environment. As a result, the simulation analysis cannot precisely forecast the impact of rising and falling interest rates on net interest income. Actual results will differ from simulated results due to many other factors, including changes in balance sheet components, interest rate changes, changes in market conditions, and management strategies. We regularly monitor our projected net interest income sensitivity to ensure that it remains within established limits. Gap analysis, the secondary method to measure IRR, measures the cash flows and/or the earliest repricing of our interest bearing assets and liabilities. This analysis is useful for measuring trends in the repricing characteristics of the balance sheet. Significant assumptions are required in this process because of the embedded repricing options contained in assets and liabilities. Residential real estate and consumer loans allow the borrower to repay the balance prior to maturity without penalty, while commercial and agricultural loans may have prepayment penalties. The amount of prepayments is dependent upon many factors, including the interest rate of a given loan in comparison to the current offering rates, the level of home sales, and the overall availability of credit in the market place. Generally, a decrease in interest rates will result in an increase in cash flows from these assets. A significant portion of our securities are callable or have prepayment options. The call and prepayment options are more likely to be exercised in a period of decreasing interest rates. Savings and demand accounts may generally be withdrawn on request without prior notice. The timing of cash flows from these deposits is estimated based on historical experience. Certificates of deposit have penalties that discourage early withdrawals. We do not believe there has been a material change in the nature or categories of our primary market risk exposure, or the particular markets that present the primary risk of loss. We do not know of or expect there to be any material change in the general nature of our primary market risk exposure in the near term, and we do not expect to make material changes to our market risk methods in the near term. We may change those methods in the future to adapt to changes in circumstances or to implement new techniques. Gap analysis is also utilized as a method to measure interest rate sensitivity. Interest rate sensitivity is determined by the amount of earning assets and interest bearing liabilities repricing within a specific time period, and their relative sensitivity to a change in interest rates. We strive to achieve reasonable stability in the net interest margin through periods of changing interest rates. One specific focus of interest rate sensitivity is the loan portfolio, primarily with commercial and agricultural loans. The following table shows the maturity of commercial and agricultural loans outstanding at December 31, 2020. Also provided are the amounts due after one year, classified according to the sensitivity to changes in interest rates. Commercial and agricultural Interest sensitivity Loans maturing after one year that have: Fixed interest rates Variable interest rates Total 1 Year or Less 1 to 5 Years Over 5 Years Total $ 179,820 $ 374,313 $ 303,014 $ 857,147 $ $ 312,450 $ 61,863 374,313 $ 116,550 186,464 303,014 Our primary market risk exposures related to the COVID-19 pandemic remain uncertain. A review of our market risk methods are ongoing and modeling is incorporating additional assumptions to account for this uncertainty related to this crisis. Repricing, cash flows, and prepayment projections for loans and mortgage-backed securities are not expected to behave as they would be expected to in a more stable interest rate environment. The SBA PPP loan is a new instrument and has payment characteristics that are still uncertain. In late March 2020, we implemented loan repayment programs for customers to alleviate the financial setback caused by the temporary closure of businesses and lost wages. Under these programs, borrowers whose loans were in good standing as of March 1, 2020 could elect to defer full or partial payments for a short period of time. Customer deposit levels may experience unusual fluctuations due to government support programs, customer and business needs, and general money supply.

Selected Financial Data. 34 Table of Contents Shareholders and Board of Directors Isabella Bank Corporation Mount Pleasant, Michigan Report of Independent Registered Public Accounting Firm Opinion on the Financial Statements and Internal Control over Financial Reporting We have audited the accompanying consolidated balance sheets of Isabella Bank Corporation as of December 31, 2020 and 2019, and the related consolidated statements of changes in shareholders’ equity, income, comprehensive income, and cash flows for each of the years in the three-year period ended December 31, 2020, and the related notes (collectively referred to as the financial statements). We also have audited Isabella Bank Corporation’s internal control over financial reporting as of December 31, 2020, based on criteria established in the Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of Isabella Bank Corporation as of December 31, 2020 and 2019, and the consolidated results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2020, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion Isabella Bank Corporation maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020, based on the COSO criteria. Basis for Opinions Isabella Bank Corporation’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express opinions on Isabella Bank Corporation’s consolidated financial statements and on Isabella Bank Corporation’s internal control over financial reporting based on our integrated audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to Isabella Bank Corporation in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material misstatement exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. We believe that our audits provide a reasonable basis for our opinions. Definition and Limitations of Internal Control over Financial Reporting A corporation’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for external purposes in accordance with generally accepted accounting principles. A corporation’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the corporation; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of consolidated financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the corporation are being made only in accordance with authorizations of management and directors of the corporation; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the corporation’s assets that could have a material effect on the consolidated financial statements. 35 Table of Contents Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. One Critical Audit Matter The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or is required to be communicated to the corporation's audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the account or disclosures to which it relates. Allowance for Loan Losses Description of the Matter The Corporation’s loan portfolio totaled $1.238 billion as of December 31, 2020 and the associated allowance for loan and lease losses (ALLL) was $9.744 million. As described in Notes 1 and 4 to the consolidated financial statements, the ALLL is established to absorb inherent losses that have been incurred or are probable within the existing portfolio of loans. Management’s estimate of inherent losses within the loan portfolio is established using quantitative, as well as qualitative, considerations. The Corporation’s methodology to determine the ALLL considers quantitative calculations including: specific valuation allowances determined in accordance with ASC Topic 310 based on probable losses on specific loans, historical valuation allowances determined in accordance with ASC topic 450 based on historical loan loss experience for similar loans with similar characteristics and trends, supplemented, as necessary, by credit judgment to address observed changes in trends and conditions, and other relevant environmental and economic factors such as concentrations of credit risk, economic trends and conditions, changes in underwriting standards, experience and depth of lending staff, trends in delinquencies, and the level of net charge-offs (qualitative factor adjustments). Auditing the Corporation’s ALLL involved a high degree of subjectivity due to the judgement involved in the management’s determination of commercial and agricultural loan credit risk ratings and identification and measurement of qualitative factor adjustments included in the estimate of the ALLL. How We Addressed the Matter in Our Audit We obtained an understanding of the Corporation’s process for establishing the ALLL and evaluated the design and tested the operating effectiveness of controls that address the risk of material misstatement related to the measurement of the ALLL. We tested controls over management’s review of commercial and agricultural loan credit risk ratings, the data inputs utilized in the ALLL calculation, management’s identification and review of the qualitative factor adjustments, and management’s review and approval process over the final determination of the ALLL. To test the commercial and agricultural loan credit risk ratings included in management’s estimate of the ALLL, we evaluated the methodology used, including management’s consideration of the individual commercial and agricultural loan portfolio segments, and tested the completeness and accuracy of data from underlying systems that was used in the determination of credit risk. We performed procedures on a sample of commercial and agricultural loans to test the Corporation’s credit risk ratings by comparing key attributes used in the determination of the credit risk rating to supporting documentation such as borrowers’ financial statements, underlying collateral, financial health of the guarantor and loan payment history. To test the measurement of qualitative factor adjustments included in management’s estimate of the ALLL, we evaluated the methodology and metrics, including testing the completeness and accuracy of data from underlying systems and other information. We further evaluated management’s assessment of the qualitative factor adjustments by obtaining an understanding of the basis for any changes in underlying qualitative factor adjustments and giving consideration to prior period qualitative factor adjustments and other information available within the Corporation and from external sources focusing on both corroborating and contrary evidence. /s/Rehmann Robson LLC We have served as Isabella Bank Corporation's independent auditor since 1996.

All intercompany balances and accounts have been eliminated in consolidation. References to “the Corporation”, “Isabella”, “we”, “our”, “us”, and similar terms refer to the consolidated entity consisting of Isabella Bank Corporation and its subsidiary. References to Isabella Bank or the “Bank” refers to Isabella Bank Corporation’s subsidiary, Isabella Bank. For additional information, see “Note 19 – Related Party Transactions.” NATURE OF OPERATIONS: Isabella Bank Corporation is a financial services holding company offering a wide array of financial products and services in several mid-Michigan counties. Our banking subsidiary, Isabella Bank, offers banking services through 30 locations, 24 hour banking services locally and nationally through shared automatic teller machines, 24 hour online banking, mobile banking, and direct deposits to businesses, institutions, individuals and their families. Lending services offered include commercial loans, agricultural loans, residential real estate loans, and consumer loans. Deposit services include interest and noninterest bearing checking accounts, savings accounts, money market accounts, certificates of deposit, direct deposits, cash management services, mobile and internet banking, electronic bill pay services, and automated teller machines. Other related financial products include trust and investment services, safe deposit box rentals, and credit life insurance. Active competition, principally from other commercial banks, savings and loan associations, mortgage brokers, finance companies, credit unions, and retail brokerage firms exists in all of our principal markets. Our results of operations can be significantly affected by changes in interest rates, changes in the local economic environment and changes in regulations. USE OF ESTIMATES: In preparing consolidated financial statements in conformity with accounting principles generally accepted in the United States of America, we make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the consolidated balance sheet and reported amounts of revenues and expenses during the reporting year. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the ALLL, the fair value of AFS investment securities, and the valuation of goodwill and other intangible assets. FAIR VALUE MEASUREMENTS: Fair value refers to the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants in the market in which the reporting entity transacts such sales or transfers based on the assumptions market participants would use when pricing an asset or liability. Assumptions are developed based on prioritizing information within a fair value hierarchy that gives the highest priority to quoted prices in active markets and the lowest priority to unobservable data, such as the reporting entity’s own data. We may choose to measure eligible items at fair value at specified election dates. For assets and liabilities recorded at fair value, it is our policy to maximize the use of observable inputs and minimize the use of unobservable inputs when developing fair value measurements for those financial instruments for which there is an active market. In cases where the market for a financial asset or liability is not active, we include appropriate risk adjustments that market participants would make for nonperformance and liquidity risks when developing fair value measurements. Fair value measurements for assets and liabilities for which limited or no observable market data exists are accordingly based primarily upon estimates, are often calculated based on the economic and competitive environment, the characteristics of the asset or liability and other factors. Therefore, the results cannot be determined with precision and may not be realized in an actual sale or immediate settlement of the asset or liability. Additionally, there may be inherent weaknesses in any calculation technique, and changes in the underlying assumptions used, including discount rates and estimates of future cash flows, could significantly affect the results of current or future values. We utilize fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. Investment securities AFS and derivative instruments are recorded at fair value on a recurring basis. Additionally, from time to time, we may be required to record other assets and liabilities at fair value on a nonrecurring basis, such as mortgage loans AFS, impaired loans, foreclosed assets, OMSR, goodwill, and certain other assets and liabilities. These nonrecurring fair value adjustments typically involve the application of lower of cost or market accounting or write downs of individual assets. 43 Table of Contents Fair Value Hierarchy Under fair value measurement and disclosure authoritative guidance, we group assets and liabilities measured at fair value into three levels, based on the markets in which the assets and liabilities are traded, and the reliability of the assumptions used to determine fair value, based on the prioritization of inputs in the valuation techniques. These levels are: Level 1: Level 2: Level 3: Valuation is based upon quoted prices for identical instruments traded in active markets. Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model based valuation techniques for which all significant assumptions are observable in the market. Valuation is generated from model based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability. The asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques maximize the use of observable inputs and minimize the use of unobservable inputs. Transfers between measurement levels are recognized at the end of reporting periods. For further discussion of fair value considerations, refer to “Note 18 – Fair Value.” SIGNIFICANT GROUP CONCENTRATIONS OF CREDIT RISK: Most of our activities are conducted with customers located within the central Michigan area. A significant amount of our outstanding loans are secured by commercial and residential real estate. Other than these types of loans, there is no significant concentration to any other industry or any one customer. CASH AND CASH EQUIVALENTS: For purposes of the consolidated statements of cash flows, cash and cash equivalents include cash and balances due from banks, federal funds sold, and other deposit accounts. Generally, federal funds sold are for a one day period. We maintain deposit accounts in various financial institutions which generally exceed federally insured limits or are not insured. We do not believe we are exposed to any significant interest, credit or other financial risk as a result of these deposits. AFS SECURITIES: Purchases of investment securities are generally classified as AFS. However, we may elect to classify securities as either held to maturity or trading. Securities classified as AFS debt securities are recorded at fair value, with unrealized gains and losses, net of the effect of deferred income taxes, excluded from earnings and reported in other comprehensive income. Included in AFS securities are auction rate money market preferred securities. These investments, for federal income tax purposes, have no federal income tax impact given the nature of the investments. Auction rate money market preferred securities are recorded at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income. Purchase premiums and discounts are recognized in interest income using the interest method over the term of the securities. Realized gains and losses on the sale of AFS securities are determined using the specific identification method. AFS securities are reviewed quarterly for possible OTTI. In determining whether an OTTI exists for debt securities, we assert that: (a) we do not have the intent to sell the security; and (b) it is more likely than not we will not have to sell the security before recovery of its cost basis. If these conditions are not met, we recognize an OTTI charge through earnings for the difference between the debt security’s amortized cost basis and its fair value, and such amount is included in noninterest income. For debt securities that do not meet the above criteria, and we do not expect to recover the security’s amortized cost basis, the security is considered other- than-temporarily impaired. For these debt securities, we separate the total impairment into the credit risk loss component and the amount of the loss related to market and other risk factors. In order to determine the amount of the credit loss for a debt security, we calculate the recovery value by performing a discounted cash flow analysis based on the current cash flows and future cash flows we expect to recover. The amount of the total OTTI related to the credit risk is recognized in earnings and is included in noninterest income. The amount of the total OTTI related to other risk factors is recognized as a component of other comprehensive income. For debt securities that have recognized OTTI through earnings, if through subsequent evaluation there is a significant increase in the cash flow expected, the difference between the amortized cost basis and the cash flows expected to be collected is accreted as interest income. LOANS: Loans that we have the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at their outstanding principal balance adjusted for any charge-offs, the ALLL, and any deferred fees or costs. Interest income on loans is accrued over the term of the loan based on the principal amount outstanding. Loan origination fees and certain direct loan origination costs are capitalized and recognized as a component of interest income over the term of the loan using the appropriate yield methods. 44 Table of Contents The accrual of interest on agricultural, commercial and mortgage loans is discontinued at the time the loan is 90 days or more past due unless the credit is well secured and in the process of collection. Consumer loans are typically charged-off no later than 180 days past due. Past due status is based on contractual terms of the loan. In all cases, loans are placed in nonaccrual or charged-off at an earlier date if collection of principal or interest is considered doubtful. For loans that are placed on nonaccrual status or charged-off, all interest accrued in the current calendar year, but not collected, is reversed against interest income while interest accrued in prior calendar years, but not collected is charged against the ALLL. Interest income on loans in nonaccrual status is not recognized until qualifying for return to accrual status. Loans are returned to accrual status when all principal and interest amounts contractually due are brought current and future payments are reasonably assured. For impaired loans not classified as nonaccrual, interest income continues to be accrued over the term of the loan based on the principal amount outstanding. ALLOWANCE FOR LOAN AND LEASE LOSSES: The ALLL is established as losses are estimated to have occurred through a provision for loan losses charged to earnings. Loan losses are charged against the allowance when we believe the uncollectability of the loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. We evaluate the ALLL on a regular basis. Our periodic review of the collectability of loans considers historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. The ALLL consists of specific, general, and unallocated components. The specific component relates to loans that are deemed to be impaired. For such loans that are analyzed for specific allowance allocations, an allowance is established when the discounted cash flows or collateral value, less costs to sell, of the impaired loan is lower than the carrying value of that loan. The general component covers non-impaired loans and is based on historical loss experience adjusted for current conditions. An unallocated component is maintained to cover uncertainties that we believe affect our estimate of probable losses based on qualitative factors. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio. Loans may be classified as impaired if they meet one or more of the following criteria: 1. 2. 3. There has been a charge-off of its principal balance; The loan has been classified as a TDR; or The loan is in nonaccrual status. Impairment is measured on a loan-by-loan basis by either the present value of expected future cash flows discounted at the loan’s effective interest rate, or the fair value of the collateral, less costs to sell, if the loan is collateral dependent. Large groups of smaller-balance, homogeneous loans are collectively evaluated for impairment. LOANS HELD FOR SALE: Mortgage loans held for sale on the secondary market are carried at the lower of cost or fair value as determined by aggregating outstanding commitments from investors or current investor yield requirements. Net unrealized losses, if any, would be recognized as a component of other noninterest expenses. Mortgage loans held for sale are sold with the mortgage servicing rights retained by us. Gains or losses on sales of mortgage loans are recognized based on the difference between the selling price and the carrying value of the related mortgage loans sold. TRANSFERS OF FINANCIAL ASSETS: Transfers of financial assets, including mortgage loans and participation loans, are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is determined to be surrendered when 1) the assets have been legally isolated from us, 2) the transferee obtains the right (free of conditions that constrain it from taking advantage of the right) to pledge or exchange the transferred assets, and 3) we do not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Other than servicing, we have no substantive continuing involvement related to these loans. SERVICING: Servicing assets are recognized as separate assets when rights are acquired through purchase or through sale of financial assets. We have no purchased servicing rights. For sales of mortgage loans, a portion of the cost of originating the loan is allocated to the servicing right based on relative fair value. Fair value is based on market prices for comparable mortgage servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the cost to service, the discount rate, the custodial earnings rate, an inflation rate, ancillary income, prepayment speeds and default rates and losses. 45 Table of Contents Servicing assets are evaluated for impairment based upon the fair value of the rights as compared to amortized cost. Impairment is determined by stratifying rights into tranches based on predominant risk characteristics, such as interest rate, loan type, and investor type. Impairment is recognized through a valuation allowance for an individual tranche, to the extent that fair value is less than the capitalized amount for the tranche. If we later determine that all or a portion of the impairment no longer exists for a particular tranche, a reduction of the valuation allowance may be recorded as an increase to income. Capitalized servicing rights are reported in other assets and are amortized into noninterest income in proportion to, and over the period of, the estimated future net servicing income of the underlying financial assets. The unpaid principal balance of mortgages serviced for others was $301,377 and $259,375 with capitalized servicing rights of $2,308 and $2,264 at December 31, 2020 and 2019, respectively, which are included in other assets. Servicing fee income is recorded for fees earned for servicing loans for others. The fees are based on a contractual percentage of the outstanding principal or a fixed amount per loan and are recorded as income when earned. We recorded servicing fee revenue of $625, $626, and $651 related to residential mortgage loans serviced for others during 2020, 2019, and 2018, respectively, which is included in other noninterest income. FORECLOSED ASSETS: Assets acquired through, or in lieu of, loan foreclosure are held for sale and are initially recorded at the lower of our carrying amount or fair value less estimated selling costs at the date of transfer, establishing a new cost basis. Any write downs based on the asset’s fair value at the date of acquisition are charged to the ALLL. After foreclosure, property held for sale is carried at the lower of the new cost basis or fair value less costs to sell. Impairment losses on property to be held and used are measured at the amount by which the carrying amount of property exceeds its fair value. Costs relating to holding these assets are expensed as incurred. We periodically perform valuations and any subsequent write downs are recorded as a charge to operations, if necessary, to reduce the carrying value of a property to the lower of our carrying amount or fair value less costs to sell. Foreclosed assets of $527 and $456 as of December 31, 2020 and 2019, respectively, are included in other assets. PREMISES AND EQUIPMENT: Land is carried at cost. Buildings and equipment are carried at cost, less accumulated depreciation which is computed principally by the straight-line method based upon the estimated useful lives of the related assets, which range from 3 to 40 years. Major improvements are capitalized and appropriately amortized based upon the useful lives of the related assets or the expected terms of the leases, if shorter, using the straight-line method. Maintenance, repairs and minor alterations are charged to current operations as expenditures occur. We annually review these assets to determine whether carrying values have been impaired. EQUITY SECURITIES WITHOUT READILY DETERMINABLE FAIR VALUES: Included in equity securities without readily determinable fair values are our holdings in FHLB stock and FRB stock as well as our joint venture investment in CSS. We sold our membership interest in CSS during the fourth quarter of 2020, which reduced equity securities without readily determinable fair values $4,246 when compared to December 31, 2019. Our investment in CSS was made in 2008. We were not the managing entity of CSS and accounted for our investment under the equity method of accounting. Equity securities without readily determinable fair values consist of the following holdings as of December 31: FHLB Stock Investment in joint venture FRB Stock Other Total 2020 2019 15,050 $ — 1,999 334 17,383 $ 15,050 4,246 1,999 334 21,629 $ $ For further discussion of our joint venture investment, refer to “Note 6 – Investment in Joint Venture.” EQUITY COMPENSATION PLANS: At December 31, 2020, the Directors Plan had 176,215 shares eligible to be issued to participants, for which the Rabbi Trust held 59,162 shares. We had 205,004 shares to be issued at December 31, 2019, with 27,069 shares held in the Rabbi Trust. Under the RSP, compensation expense for nonvested stock awards is based on the fair value of the award on the measurement date. The fair value of nonvested stock awards is based on the date of the grant and is recognized over the requisite service period. The impact of forfeitures of share-based payment awards on compensation expense is recognized as forfeitures occur. Compensation costs relating to share-based payment transactions are recognized as the services are rendered, with the cost measured based on the fair value of the equity or liability instruments issued (see “Note 13 – Benefit Plans”). 46 Table of Contents CORPORATE OWNED LIFE INSURANCE: We have purchased life insurance policies on key members of management, partially for the purpose of funding certain post-retirement benefits. In the event of death of one of these individuals, we would receive a specified cash payment equal to the face value of the policy. Such policies are recorded at their cash surrender value, or the amount that can be realized on the balance sheet date. Increases in cash surrender value in excess of single premiums paid are reported as other noninterest income. Of the purchased life insurance policies, we hold post retirement benefits with a present value estimated to be $2,810 and $2,875 as of December 31, 2020 and 2019, respectively, which is included in accrued interest payable and other liabilities. The expenses associated with these policies totaled $87, $125, and $0 for 2020, 2019, and 2018, respectively. ACQUISITION INTANGIBLES AND GOODWILL: We previously acquired branch facilities and related deposits in business combinations accounted for as a purchase. The acquisitions included amounts related to the valuation of customer deposit relationships (core deposit intangibles). Core deposit intangibles arising from acquisitions are included in goodwill and other intangible assets are being amortized over their estimated lives and evaluated for potential impairment on at least an annual basis. Goodwill, which represents the excess of the purchase price over identifiable assets, is not amortized but is evaluated for impairment on at least an annual basis. Acquisition intangibles and goodwill are typically qualitatively evaluated to determine if it is more likely than not that the carrying balance is impaired. If it is determined that the carrying balance is more likely than not to be impaired, we perform a cash flow valuation to determine the extent of the potential impairment. This valuation method requires a significant degree of our judgment. In the event the projected undiscounted net operating cash flows for these intangible assets are less than the carrying value, the asset is recorded at fair value as determined by the valuation model. OFF BALANCE SHEET CREDIT RELATED FINANCIAL INSTRUMENTS: In the ordinary course of business, we have entered into commitments to extend credit, including commitments under credit card arrangements, commercial lines of credit, home equity lines of credit, commercial letters of credit, and standby letters of credit. Such financial instruments are recorded only when funded. REVENUE RECOGNITION: Our revenue is comprised primarily of interest income, service charges and fees, gains on the sale of loans and AFS securities, earnings on corporate owned life insurance policies, and other noninterest income. Other noninterest income is typically service and performance driven in nature and comprised primarily of investment and trust advisory fees. We recognize revenue, excluding interest income and other income specifically scoped out, in accordance with ASC 606, Revenue From Contracts with Customers. Revenue is recognized when our performance obligation has been satisfied according to our contractual obligation. FEDERAL INCOME TAXES: Deferred income tax assets and liabilities are determined using the liability (or balance sheet) method. Under this method, the net deferred tax assets or liabilities are determined based on the tax effects of the temporary differences between the book and tax basis on the various balance sheet assets and liabilities and gives current recognition to changes in tax rates and laws. Valuation allowances are established, where necessary, to reduce deferred tax assets to the amount expected to be realized. Income tax expense is the tax payable or refundable for the year plus or minus the change during the year in deferred tax assets and liabilities. We analyze our filing positions in the jurisdictions where we are required to file income tax returns, as well as all open tax years in these jurisdictions. We also treat interest and penalties attributable to income taxes, to the extent they arise, as a component of our noninterest expenses. DEFINED BENEFIT PENSION PLAN: We maintain a noncontributory defined benefit pension plan, which was curtailed effective March 1, 2007. The service cost component of the defined benefit pension plan is included in “compensation and benefits” on the consolidated statements of income and is funded consistent with the requirements of federal laws and regulations. All other costs related to the defined benefit pension plan are included in “other” noninterest expenses on the consolidated statements of income. The current benefit obligation is included in "accrued interest payable and other liabilities" on the consolidated balance sheets. Inherent in the determination of defined benefit pension costs are assumptions concerning future events that will affect the amount and timing of required benefit payments under the plan. These assumptions include demographic assumptions such as mortality, a discount rate used to determine the current benefit obligation and a long-term expected rate of return on plan assets. Net periodic benefit cost includes the interest cost based on the assumed discount rate, an expected return on plan assets based on an actuarially derived market-related value of assets, and amortization of unrecognized net actuarial gains or losses. Actuarial gains and losses result from experience different from that assumed and from changes in assumptions (excluding asset gains and losses not yet reflected in market-related value). Amortization of actuarial gains and losses is included as a component of net periodic defined benefit pension cost. For additional information, see “Note 13 – Benefit Plans.” 47 Table of Contents MARKETING COSTS: Marketing costs are expensed as incurred (see “Note 15 – Other Noninterest Expenses”). RECLASSIFICATIONS: Certain amounts reported in the 2019 and 2018 consolidated financial statements have been reclassified to conform with the 2020 presentation. All other balances and ratios were not materially impacted. Other assets and other liabilities on the consolidated balance sheets were decreased by $1,555 as of December 31, 2019 to reclassify pension liabilities. This resulted in a $1,555 decrease in total assets and total liabilities as of December 31, 2019. All other balances and ratios were not materially impacted. Note 2 – Accounting Standards Updates Recently Adopted Accounting Standards Updates ASU No. 2018-13: “Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement” In August 2018, ASU No. 2018-13 was issued and provided an updated framework related to fair value disclosures. For entities required to make disclosures about recurring or nonrecurring fair value measurements, the update provides disclosure modifications which include the removal, modification and addition of specific disclosure requirements. The new authoritative guidance was effective January 1, 2020 and did not have a significant impact on our financial statement disclosures. ASU No. 2018-14: “Compensation - Retirement Benefits - Defined Pension Plans - General (Subtopic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans” In August 2018, ASU No. 2018-14 was issued and provided an updated framework related to defined benefit plans. For employers that sponsor defined benefit pension or other postretirement plans, the update provides disclosure modifications which include the removal of six specific requirements, the addition of two specific requirements and clarification to existing requirements. Disclosure additions include 1) the weighted-average interest crediting rates for cash balance plans and other plans with promised interest crediting rates; 2) an explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period. Clarification items relate to 1) the projected benefit obligation (PBO) and fair value of plan assets for plans with PBOs in excess of plan assets; and 2) the accumulated benefit obligation (ABO) and fair value of plan assets for plans with ABOs in excess of plan assets. The new authoritative guidance was effective for fiscal years ending after December 15, 2020 and did not have a significant impact on our financial statement disclosures. ASU No. 2018-15: “Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract” In August 2018, ASU No. 2018-15 was issued and provided guidance on the accounting for implementation, setup, and other upfront costs (collectively referred to as implementation costs) for entities that are a customer in a hosting arrangement that is a service contract. The guidance also provided clarification on requirements to capitalize implementation costs and the required accounting for expenses related to capitalization of implementation costs. The new authoritative guidance was effective January 1, 2020. We will review arrangements entered into prospectively. These changes are not expected to have a significant impact on our operating results or financial statement disclosures. Pending Accounting Standards Updates ASU No. 2016-13: “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” In June 2016, ASU No. 2016-13 was issued and updated the measurement for credit losses for AFS debt securities and assets measured at amortized cost which include loans, trade receivables, and any other financial assets with the contractual right to receive cash. Current GAAP requires an “incurred loss” methodology for recognizing credit losses that delays recognition until it is probable a loss has been incurred. Under the incurred loss approach, entities are limited to a probable initial recognition threshold when credit losses are measured; an entity generally only considers past events and current conditions in measuring the incurred loss. 48 Table of Contents Under the new guidance, the incurred loss impairment methodology in current GAAP is replaced with a methodology that reflects current expected credit losses (CECL). This methodology requires consideration of a broader range of reasonable and supportable information to calculate credit loss estimates. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. An entity must use judgment in determining the relevant information and estimation methods that are appropriate in its circumstances which applies to assets measured either collectively or individually. The update allows an entity to revert to historical loss information that is reflective of the contractual term (considering the effect of prepayments) for periods that are beyond the time frame for which the entity is able to develop reasonable and supportable forecasts. In addition, the disclosures of credit quality indicators in relation to the amortized cost of financing receivables, a current disclosure requirement, are further disaggregated by year of origination (or vintage). The vintage information will be useful for financial statement users to better assess changes in underwriting standards and credit quality trends in asset portfolios over time and the effect of those changes on credit losses. Overall, the update will allow entities the ability to measure expected credit losses without the restriction of incurred or probable losses that exist under current GAAP. For users of the financial statements, the update requires disclosure of 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 new authoritative guidance was effective for interim and annual periods beginning after December 15, 2019 for select filers. Effective October 16, 2019, the FASB approved changes to the implementation date of this guidance for some filers. As a small reporting company, as defined by the SEC, our implementation date was delayed from January 1, 2020 to January 1, 2023. Early adoption continues to be permissible under the revised implementation date. This guidance may have a significant impact on our operations and financial statement disclosures as well as that of the banking industry as a whole. We have invested a considerable amount of effort toward this guidance and will continue to invest considerable effort until our implementation date. An internal committee was formed and is accountable for timely and accurate adoption of the guidance. A service provider that has focused on the ALLL for more than 10 years and serves hundreds of financial institutions has been engaged to provide us with education, advisory, and software solutions exclusively related to the ACL. We will run parallel processes which will help to ensure we are ready to calculate, review, and report the ACL by the required implementation date. Note 3 – AFS Securities The amortized cost and fair value of AFS securities, with gross unrealized gains and losses, are as follows as of December 31: States and political subdivisions Auction rate money market preferred Mortgage-backed securities Collateralized mortgage obligations Corporate Total States and political subdivisions Auction rate money market preferred Mortgage-backed securities Collateralized mortgage obligations Total 2020 Gross Unrealized Gains Gross Unrealized Losses 5,946 $ 37 2,726 4,553 — 13,262 $ 2019 Gross Unrealized Gains Gross Unrealized Losses 4,747 $ — 933 1,007 6,687 $ Fair Value 143,656 3,237 88,652 101,983 1,700 339,228 Fair Value 169,752 3,119 140,204 116,764 429,839 — — — — — — — 81 560 187 828 $ $ $ $ Amortized Cost 137,710 $ 3,200 85,926 97,430 1,700 325,966 $ Amortized Cost 165,005 $ 3,200 139,831 115,944 423,980 $ $ $ $ $ 49 Table of Contents The amortized cost and fair value of AFS securities by contractual maturity at December 31, 2020 are as follows: States and political subdivisions Auction rate money market preferred Mortgage-backed securities Collateralized mortgage obligations Corporate Total amortized cost Fair value Due in One Year or Less Maturing After One Year But Within Five Years After Five Years But Within Ten Years Securities with Variable Monthly Payments or Noncontractual Maturities After Ten Years $ $ $ 23,754 $ — — — — 23,754 $ 23,922 $ 63,781 $ — — — — 63,781 $ 65,462 $ 24,055 $ — — — 1,700 25,755 $ 26,990 $ 26,120 $ — — — — 26,120 $ 28,982 $ — $ 3,200 85,926 97,430 — 186,556 $ 193,872 $ Total 137,710 3,200 85,926 97,430 1,700 325,966 339,228 Expected maturities for government sponsored enterprises and states and political subdivisions may differ from contractual maturities because issuers may have the right to call or prepay obligations. As the auction rate money market preferred investments have continual call dates, they are not reported by a specific maturity group. Because of their variable monthly payments, mortgage-backed securities and collateralized mortgage obligations are not reported by a specific maturity group. A summary of the sales activity of AFS securities during the years ended December 31 is displayed in the following table. Proceeds from sales of AFS securities Realized gains (losses) Applicable income tax expense (benefit) 2020 2019 2018 26,855 $ 33,840 $ 71 $ 15 $ 6 $ 1 $ — — — $ $ $ The following information pertains to AFS securities with gross unrealized losses at December 31 aggregated by investment category and length of time that individual securities have been in a continuous loss position. There were no AFS securities with gross unrealized losses in a continuous loss position at December 31, 2020. Auction rate money market preferred Mortgage-backed securities Collateralized mortgage obligations Total Number of securities in an unrealized loss position: Less Than Twelve Months Gross Unrealized Losses Fair Value 2019 Twelve Months or More Gross Unrealized Losses Fair Value — 3 43 46 $ — 3,974 20,262 24,236 $ 9 81 557 144 782 $ 3,119 49,701 13,309 66,129 $ 19 $ Total Unrealized Losses 81 560 187 828 28 The reduction in unrealized losses on our AFS securities portfolio resulted from recent decreases in intermediate-term and long-term benchmark interest rates. As of December 31, 2020 and 2019, we conducted an analysis to determine whether any AFS securities currently in an unrealized loss position should be identified as other-than-temporarily impaired. Such analyses considered, among other factors, the following criteria: • • • • • Has the value of the investment declined more than what is deemed to be reasonable based on a risk and maturity adjusted discount rate? Is the investment credit rating below investment grade? Is it probable the issuer will be unable to pay the amount when due? Is it more likely than not that we will have to sell the security before recovery of its cost basis? Has the duration of the investment been extended? 50 Table of Contents Based on our analysis, which included the criteria outlined above and the fact that we have asserted that we do not have to sell any AFS securities in an unrealized loss position, we do not believe that the values of any AFS securities are other-than-temporarily impaired as of December 31, 2020 and 2019, with the exception of one municipal bond previously identified which had no activity during the period. Note 4 – Loans and ALLL We grant commercial, agricultural, residential real estate, and consumer loans to customers situated primarily in Clare, Gratiot, Isabella, Mecosta, Midland, Montcalm, and Saginaw counties in Michigan. The ability of the borrowers to honor their repayment obligations is often dependent upon the real estate, agricultural, manufacturing, retail, gaming, tourism, higher education, and general economic conditions of this region. Substantially all of our consumer and residential real estate loans are secured by various items of property, while commercial loans are secured primarily by real estate, business assets, and personal guarantees. A portion of loans are unsecured. Loans that we have the intent and ability to hold in our portfolio are reported at their outstanding principal balance adjusted for any charge-offs, the ALLL, and any deferred fees or costs. Interest income is accrued over the term of the loan based on the principal amount outstanding. Loan origination fees and certain direct loan origination costs are capitalized and recognized as a component of interest income over the term of the loan using the appropriate amortization methods. The accrual of interest on commercial and agricultural loans, as well as residential real estate loans, is discontinued at the time a loan is 90 days or more past due unless the credit is well-secured and in the process of short-term collection. Upon transferring a loan to nonaccrual status, we perform an evaluation to determine the net realizable value of the underlying collateral. This evaluation is used to help determine if a charge-off is necessary. Consumer loans are typically charged-off no later than 180 days past due. Past due status is based on the contractual term of the loan. In all cases, a loan is placed in nonaccrual status or charged-off at an earlier date if collection of principal or interest is considered doubtful. When a loan is placed in nonaccrual status or charged-off, all interest accrued in the current calendar year, but not collected, is reversed against interest income while interest accrued in prior calendar years, but not collected, is charged against the ALLL. Loans may be returned to accrual status after six months of continuous performance and achievement of current payment status. Commercial and agricultural loans include loans for commercial real estate, commercial operating loans, advances to mortgage brokers, farmland and agricultural production, and loans to states and political subdivisions. Repayment of these loans is dependent upon the successful operation and management of a business. We minimize our risk by limiting the amount of direct credit exposure to any one borrower to $15,000. Borrowers with direct credit needs of more than $15,000 may be serviced through the use of loan participations with other commercial banks. Commercial and agricultural real estate loans commonly require loan-to-value limits of 80% or less. Depending upon the type of loan, past credit history, and current operating results, we may require the borrower to pledge accounts receivable, inventory, property, or equipment. Personal guarantees are generally required from the owners of closely held corporations, partnerships, and sole proprietorships. In addition, we may require annual financial statements, prepare cash flow analyses, and review credit reports. We entered into a mortgage purchase program in 2016 with a financial institution where we participate in advances to mortgage brokers (“advances”). The mortgage brokers originate residential mortgage loans with the intent to sell them on the secondary market. We participate in the advance to the mortgage broker, which is secured by the underlying mortgage loan, until it is ultimately sold on the secondary market. As such, the average life of each participated advance is approximately 20-30 days. Funds from the sale of the loan are used to pay off our participation in the advance to the mortgage broker. We classify these advances as commercial loans and include the outstanding balance in commercial loans on our consolidated balance sheets. Under the participation agreement, we committed to a maximum outstanding aggregate amount of $80,000 as of December 31, 2020. During the first quarter of 2021, the maximum outstanding aggregate amount was reduced to $40,000. The difference between our outstanding balance and the maximum outstanding aggregate amount is classified as “Unfunded commitments under lines of credit” in the “Contractual Obligations and Loan Commitments” section of the Management's Discussion and Analysis of Financial Condition and Results of Operations of this report. We offer adjustable rate mortgages, construction loans, and fixed rate residential real estate loans which have amortization periods up to a maximum of 30 years. We consider the anticipated direction of interest rates, balance sheet duration, the sensitivity of our balance sheet to changes in interest rates, our liquidity needs, and overall loan demand to determine whether or not to sell fixed rate loans to Freddie Mac. Our lending policies generally limit the maximum loan-to-value ratio on residential real estate loans to 100% of the lower of the appraised value of the property or the purchase price. Private mortgage insurance is typically required on loans with loan-to-value ratios in excess of 80% unless the loan qualifies for government guarantees. 51 Table of Contents Underwriting criteria for residential real estate loans generally include: • • • • • • Evaluation of the borrower’s ability to make monthly payments. Evaluation of the value of the property securing the loan. Ensuring the payment of principal, interest, taxes, and hazard insurance does not exceed 28% of a borrower’s gross income. Ensuring all debt servicing does not exceed 40% of income. Verification of acceptable credit reports. Verification of employment, income, and financial information. Appraisals are performed by independent appraisers and are reviewed for appropriateness. Generally, mortgage loan requests are reviewed by our mortgage loan committee or through a secondary market underwriting system; loans in excess of $1,000 require the approval of our Internal Loan Committee, the Executive Loan Committee, the Board of Directors’ Loan Committee, or the Board of Directors. Consumer loans include secured and unsecured personal loans. Loans are amortized for a period of up to 15 years based on the age and value of the underlying collateral. The underwriting emphasis is on a borrower’s perceived intent and ability to pay rather than collateral value. No consumer loans are sold to the secondary market. The ALLL is established as losses are estimated to have occurred through a provision for loan losses charged to earnings. Loan losses are charged against the ALLL when we believe the uncollectability of the loan balance is probable. Subsequent recoveries, if any, are credited to the ALLL. The ALLL is evaluated on a regular basis for appropriateness. Our periodic review of the collectability of a loan considers historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral, and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. The primary factors behind the determination of the level of the ALLL are specific allocations for impaired loans, historical loss percentages, as well as unallocated components. Specific allocations for impaired loans are primarily determined based on the difference between the loan’s outstanding balance and the present value of expected future cash flows discounted at the loan’s effective interest rate, or the fair value of the collateral, less costs to sell, if the loan is collateral dependent. Historical loss allocations are calculated at the loan class and segment levels based on a migration analysis of the loan portfolio, with the exception of advances to mortgage brokers, over the preceding five years. With no historical losses on advances to mortgage brokers, there is no allocation in the commercial segment displayed in the following tables. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio. A summary of changes in the ALLL and the recorded investment in loans by segments follows: January 1, 2020 Charge-offs Recoveries Provision for loan losses December 31, 2020 Commercial Agricultural Allowance for Loan Losses Year Ended December 31, 2020 Residential Real Estate Consumer Unallocated Total $ $ 1,914 $ (7) 149 106 2,162 $ 634 (24) 39 (338) 311 $ $ 2,047 $ (28) 136 (792) 1,363 $ 922 $ (322) 197 1 798 $ 2,422 $ — — 2,688 5,110 $ 7,939 (381) 521 1,665 9,744 52 Table of Contents January 1, 2019 Charge-offs Recoveries Provision for loan losses December 31, 2019 ALLL Individually evaluated for impairment Collectively evaluated for impairment Total Loans Individually evaluated for impairment Collectively evaluated for impairment Total ALLL Individually evaluated for impairment Collectively evaluated for impairment Total Loans Individually evaluated for impairment Collectively evaluated for impairment Total Commercial Agricultural Allowance for Loan Losses Year Ended December 31, 2019 Residential Real Estate Consumer Unallocated Total $ $ 2,563 $ (143) 123 (629) 1,914 $ 775 (240) 3 96 634 $ $ 1,992 $ (99) 189 (35) 2,047 $ 857 $ (466) 167 364 922 $ 2,188 $ — — 234 2,422 $ 8,375 (948) 482 30 7,939 Allowance for Loan Losses and Recorded Investment in Loans As of December 31, 2020 Commercial Agricultural Residential Real Estate Consumer Unallocated Total 84 $ 2,078 2,162 $ 56 $ 255 311 $ 771 $ 592 1,363 $ — $ 798 798 $ — $ 5,110 5,110 $ 911 8,833 9,744 9,821 $ 746,865 756,686 $ 13,796 $ 86,665 100,461 $ 4,319 $ 303,224 307,543 $ — 73,621 73,621 $ $ 27,936 1,210,375 1,238,311 Allowance for Loan Losses and Recorded Investment in Loans As of December 31, 2019 Commercial Agricultural Residential Real Estate Consumer Unallocated Total 15 $ 1,899 1,914 $ 26 $ 608 634 $ 1,073 $ 974 2,047 $ — $ 922 922 $ — $ 2,422 2,422 $ 1,114 6,825 7,939 7,865 $ 693,076 700,941 $ 14,840 $ 102,080 116,920 $ 5,486 $ 293,083 298,569 $ — 70,140 70,140 $ $ 28,191 1,158,379 1,186,570 $ $ $ $ $ $ $ $ 53 Table of Contents The following tables display the credit quality indicators for commercial and agricultural credit exposures based on internally assigned credit risk ratings as of December 31: Real Estate Other Commercial Advances to Mortgage Brokers 2020 Agricultural Total Real Estate Other Total Total Total $ Rating 1 - Excellent 2 - High quality 3 - High satisfactory 4 - Low satisfactory 5 - Special mention 6 - Substandard 7 - Vulnerable 8 - Doubtful 9 - Loss Rating 1 - Excellent 2 - High quality 3 - High satisfactory 4 - Low satisfactory 5 - Special mention 6 - Substandard 7 - Vulnerable 8 - Doubtful 9 - Loss $ — $ — $ 2,308 69,327 403,733 15,049 15,854 26 — — 506,297 $ 13,406 51,093 122,025 6,174 6,130 1,303 — — 200,131 $ — $ — 50,258 — — — — — — 50,258 $ — $ 15,714 170,678 525,758 21,223 21,984 1,329 — — 756,686 $ 2019 — $ 541 14,411 34,464 13,137 5,267 3,208 190 — 71,218 $ — $ 11 5,312 17,600 3,240 2,693 387 — — 29,243 $ — $ 552 19,723 52,064 16,377 7,960 3,595 190 — 100,461 $ — 16,266 190,401 577,822 37,600 29,944 4,924 190 — 857,147 Real Estate Other Commercial Advances to Mortgage Brokers Agricultural Total Real Estate Other Total Total $ — $ 390 $ 2,582 109,737 377,198 15,372 4,874 390 — — 510,153 $ 8,844 42,858 94,847 3,470 3,625 1,231 — — 155,265 $ — $ — 35,523 — — — — — — 35,523 $ 390 $ 11,426 188,118 472,045 18,842 8,499 1,621 — — 700,941 $ — $ 1,452 16,765 42,798 7,165 9,136 2,711 — — 80,027 $ — $ 99 6,769 20,861 3,754 3,836 1,574 — — 36,893 $ — $ 1,551 23,534 63,659 10,919 12,972 4,285 — — 116,920 $ 390 12,977 211,652 535,704 29,761 21,471 5,906 — — 817,861 Total $ Internally assigned credit risk ratings are reviewed, at a minimum, when loans are renewed or when management has knowledge of improvements or deterioration of the credit quality of individual credits. Descriptions of the internally assigned credit risk ratings for commercial and agricultural loans are as follows: 1. EXCELLENT – Substantially Risk Free Credit has strong financial condition and solid earnings history, characterized by: • • • • High liquidity, strong cash flow, low leverage. Unquestioned ability to meet all obligations when due. Experienced management, with management succession in place. Secured by cash. 54 Table of Contents 2. HIGH QUALITY – Limited Risk Credit with sound financial condition and a positive trend in earnings supplemented by: • • Favorable liquidity and leverage ratios. Ability to meet all obligations when due. • Management with successful track record. • • • Steady and satisfactory earnings history. If loan is secured, collateral is of high quality and readily marketable. Access to alternative financing. • Well defined primary and secondary source of repayment. • If supported by guaranty, the financial strength and liquidity of the guarantor(s) are clearly evident. 3. HIGH SATISFACTORY – Reasonable Risk Credit with satisfactory financial condition and further characterized by: • Working capital adequate to support operations. • Cash flow sufficient to pay debts as scheduled. • Management experience and depth appear favorable. • • Loan performing according to terms. If loan is secured, collateral is acceptable and loan is fully protected. 4. LOW SATISFACTORY – Acceptable Risk Credit with bankable risks, although some signs of weaknesses are shown: • Would include most start-up businesses. • Occasional instances of trade slowness or repayment delinquency – may have been 10-30 days slow within the past year. • Management’s abilities are apparent yet unproven. • Weakness in primary source of repayment with adequate secondary source of repayment. • • Loan structure generally in accordance with policy. If secured, loan collateral coverage is marginal. To be classified as less than satisfactory, only one of the following criteria must be met. 5. SPECIAL MENTION – Criticized Credit constitutes an undue and unwarranted credit risk but not to the point of justifying a classification of substandard. The credit risk may be relatively minor yet constitutes an unwarranted risk in light of the circumstances surrounding a specific loan: • • • • • • Downward trend in sales, profit levels, and margins. Impaired working capital position. Cash flow is strained in order to meet debt repayment. Loan delinquency (30-60 days) and overdrafts may occur. Shrinking equity cushion. Diminishing primary source of repayment and questionable secondary source. • Management abilities are questionable. • Weak industry conditions. • Litigation pending against the borrower. 55 Table of Contents • • • Loan may need to be restructured to improve collateral position or reduce payments. Collateral or guaranty offers limited protection. Negative debt service coverage, however the credit is well collateralized and payments are current. 6. SUBSTANDARD – Classified Credit is inadequately protected by the current net worth and paying capacity of the borrower or of the collateral pledged. There is a distinct possibility we will implement collection procedures if the loan deficiencies are not corrected. Any commercial loan placed in nonaccrual status will be rated “7” or worse. In addition, the following characteristics may apply: • • • • • • • • • • • • Sustained losses have severely eroded the equity and cash flow. Deteriorating liquidity. Serious management problems or internal fraud. Original repayment terms liberalized. Likelihood of bankruptcy. Inability to access other funding sources. Reliance on secondary source of repayment. Litigation filed against borrower. Interest non-accrual may be warranted. Collateral provides little or no value. Requires excessive attention of the loan officer. Borrower is uncooperative with loan officer. 7. VULNERABLE – Classified Credit is considered “Substandard” and warrants placing in nonaccrual status. Risk of loss is being evaluated and exit strategy options are under review. Other characteristics that may apply: • Insufficient cash flow to service debt. • Minimal or no payments being received. • • Limited options available to avoid the collection process. Transition status, expect action will take place to collect loan without immediate progress being made. 8. DOUBTFUL – Workout Credit has all the weaknesses inherent in a “Substandard” loan with the added characteristic that collection and/or liquidation is pending. The possibility of a loss is extremely high, but its classification as a loss is deferred until liquidation procedures are completed, or reasonably estimable. Other characteristics that may apply: • • • • • • • • • Normal operations are severely diminished or have ceased. Seriously impaired cash flow. Original repayment terms materially altered. Secondary source of repayment is inadequate. Survivability as a “going concern” is impossible. Collection process has begun. Bankruptcy petition has been filed. Judgments have been filed. Portion of the loan balance has been charged-off. 56 Table of Contents 9. LOSS – Charge-off Credit is considered uncollectible and of such little value that their continuance as bankable assets is not warranted. This classification is for charged-off loans but does not mean that the asset has absolutely no recovery or salvage value. These loans are further characterized by: • • • • • Liquidation or reorganization under Bankruptcy, with poor prospects of collection. Fraudulently overstated assets and/or earnings. Collateral has marginal or no value. Debtor cannot be located. Over 120 days delinquent. Our primary credit quality indicator for residential real estate and consumer loans is the individual loan’s past due aging.

There has been a charge-off of its principal balance (in whole or in part); 2. The loan has been classified as a TDR; or 3. The loan is in nonaccrual status. Impairment is measured on a loan-by-loan basis for commercial and agricultural loans by comparing the loan’s outstanding balance to the present value of expected future cash flows discounted at the loan’s effective interest rate, or the fair value of the collateral, less costs to sell, if the loan is collateral dependent. Large groups of smaller-balance, homogeneous residential real estate and consumer loans are collectively evaluated for impairment by comparing the loan’s unpaid principal balance to the present value of expected future cash flows discounted at the loan’s effective interest rate. 58 Table of Contents We do not recognize interest income on impaired loans in nonaccrual status. For impaired loans not classified as nonaccrual, interest income is recognized daily, as earned, according to the terms of the loan agreement and the principal amount outstanding.

Troubled Debt Restructurings A loan modification is considered to be a TDR when the modification includes terms outside of normal lending practices to a borrower who is experiencing financial difficulties. Typical concessions granted include, but are not limited to: 1. Agreeing to interest rates below prevailing market rates for debt with similar risk characteristics. 2. Extending the amortization period beyond typical lending guidelines for loans with similar risk characteristics. 3. Agreeing to an interest only payment structure and delaying principal payments. 4. Forgiving principal. 5. Forgiving accrued interest. To determine if a borrower is experiencing financial difficulties, factors we consider include: 1. The borrower is currently in default on any of their debt. 2. The borrower would likely default on any of their debt if the concession is not granted. 3. The borrower’s cash flow is insufficient to service all of their debt if the concession is not granted. 4. The borrower has declared, or is in the process of declaring, bankruptcy. 5. The borrower is unlikely to continue as a going concern (if the entity is a business). 60 Table of Contents The following is a summary of information pertaining to TDRs granted in the years ended December 31: Commercial other Agricultural other Residential real estate Total 2020 Pre-Modification Recorded Investment Post-Modification Recorded Investment 5,224 $ 3,194 136 8,554 $ 5,224 3,194 136 8,554 Number of Loans 10 5 3 18 $ $ 2019 Pre-Modification Recorded Investment Post-Modification Recorded Investment 1,188 $ 3,286 17 4,491 $ 1,188 3,286 17 4,491 Number of Loans 3 7 1 11 $ $ The following table summarizes the nature of the concessions we granted to borrowers in financial difficulty in the years ended December 31: 2020 2019 Below Market Interest Rate Below Market Interest Rate and Extension of Amortization Period Below Market Interest Rate Below Market Interest Rate and Extension of Amortization Period Number of Loans Pre-Modification Recorded Investment Number of Loans Pre- Modification Recorded Investment Number of Loans Pre- Modification Recorded Investment Number of Loans Pre- Modification Recorded Investment 2 — — 2 $ $ 987 — — 987 8 5 3 16 $ $ 4,237 3,194 136 7,567 — 2 — 2 $ $ — 1,189 — 1,189 3 5 1 9 $ $ 1,188 2,097 17 3,302 Commercial other Agricultural other Residential real estate Total We did not restructure any loans by forgiving principal or accrued interest during 2020 or 2019. Based on our historical loss experience, losses associated with TDRs are not significantly different than other impaired loans within the same loan segment. As such, TDRs, including TDRs that have been modified in the past 12 months that subsequently defaulted, are analyzed in the same manner as other impaired loans within their respective loan segment. We had no loans that defaulted in the years ended December 31, 2020 and 2019, which were modified within 12 months prior to the default date. The following is a summary of TDR loan balances as of December 31: TDRs 2020 2019 $ 24,930 $ 24,737 Measures we have taken to assist our customers include loan programs that provide short-term payment relief. Under these programs, borrowers whose loans were in good standing as of March 1, 2020 could elect to defer full or partial payments for a period not to exceed 180 days. Loan payment deferrals totaled $306,103, or 23.8% of gross loans, as of June 30, 2020. As of September 30, 2020, active loan payment deferrals declined to $103,858, or 8.0% of gross loans, as the majority of borrowers granted loan payment deferrals had reverted back to contractual payments. As of December 31, 2020, active loan payment deferrals declined even further and totaled $6,048, or 0.5% of gross loans. Bank regulators issued a statement on March 22, 2020, and a revised statement on April 7, 2020, which provided confirmation that short-term loan modifications made on a good faith basis in response to COVID-19 to borrowers with a current payment status are not categorized as TDRs. Pursuant to this guidance, borrowers granted a short-term loan modification meeting this criteria were not categorized as TDR as of December 31, 2020. 61 Table of Contents Note 5 – Premises and Equipment A summary of premises and equipment at December 31 follows: Land Buildings and improvements Furniture and equipment Total Less: accumulated depreciation Premises and equipment, net 2020 2019 6,164 $ 30,503 35,896 72,563 47,423 25,140 $ 6,336 30,257 35,121 71,714 45,472 26,242 $ $ Depreciation expense amounted to $2,620, $2,908, and $2,940 in 2020, 2019, and 2018, respectively. Note 6 – Investment in Joint Venture In 2008, we merged the assets of our wholly owned subsidiary, IBT Title and Insurance Agency, Inc. (“IBT Title”) into a 50/50 joint venture with Corporate Title Agency, LLC, a third-party business based in Traverse City, Michigan, to form CSS. The purpose of the joint venture was to help IBT Title expand its service area and to take advantage of economies of scale. As a 50% owner of the membership units of this entity, we accounted for our investment under the equity method of accounting, and our share of income and loss from the joint venture is included in noninterest income. CSS is a limited liability company. Therefore, federal taxable income and deductions are passed through to the members, and no provision for federal income taxes is reflected in the condensed statements of income. During the second half of 2019, a new line of business was proposed by the CSS General Manager which did not interest us as it was unrelated to the Bank's core business. Subsequently, the General Manager of CSS chose to have a company valuation performed by a third party during the fourth quarter of 2019 for purposes of investor planning. The independent, third-party valuation identified that CSS’ intangible assets required an impairment of $7,133. As a 50% owner of the membership units of CSS, we recognized the reduced value of our investment which resulted in a reduction to income of $3,566 in the fourth quarter of 2019. We sold our membership interest in CSS during the fourth quarter of 2020, which reduced equity securities without readily determinable fair values $4,246 when compared to December 31, 2019. As a result of this transaction, we received a $1,000 down payment, recorded a receivable in the amount of $3,227 and recorded a loss of $394. In 2020, our share of income was $577, including the reduction of $394 from the sale. Note 7 – Goodwill and Other Intangible Assets Goodwill represents the excess of the amounts paid to acquire subsidiaries over the fair value of their net assets at the date of acquisition. The majority of the recorded goodwill is related to acquisitions of other banks, which were subsequently merged into Isabella Bank. If it is determined that the goodwill is impaired, a write-down of goodwill by the amount of the impairment would be required. The carrying amount of goodwill was $48,282 at December 31, 2020 and 2019. The decline in economic conditions, as a result of the COVID-19 pandemic and other factors, led to a significant decline in the stock market causing the value of investments, including our stock, to decline. Our stock price was negatively impacted in March 2020, which continued during most of 2020. Since the price of our stock increased but had not fully recovered through the fourth quarter, we decided to engage a third-party valuation firm to perform a quantitative analysis of goodwill as of December 31, 2020. In determining the fair value of the Bank and Isabella Bank Corporation, the third-party firm assessed general economic conditions, industry and market considerations, the impact of recent events to financial performance, the market price of our common stock, and other relevant events. Based on the valuation prepared, it was determined that our estimated fair values of the Bank and Isabella Bank Corporation at December 31, 2020 were greater than our recorded book value and no impairment of goodwill was identified. Furthermore, management noted that despite the decline of the market capitalization as a result of the COVID-19 pandemic, our financial performance remained positive. This is evidenced by our financial results, strong credit quality indicators, increased liquidity position, as well as the strong capital position. Finally, by the end of the fourth quarter, our stock price had increased to levels consistent with prices prior to the second quarter of 2020. Based on these factors and the results of the independent quantitative analysis of goodwill, management concluded that it was more likely than not that there was no goodwill impairment as of December 31, 2020. 62 Table of Contents Identifiable intangible assets were as follows as of December 31: Core deposit premium resulting from acquisitions Core deposit premium resulting from acquisitions Gross Intangible Assets 2020 Accumulated Amortization Net Intangible Assets 5,579 $ 5,530 $ 49 Gross Intangible Assets 2019 Accumulated Amortization Net Intangible Assets 5,579 $ 5,482 $ 97 $ $ Amortization expense associated with identifiable intangible assets was $48, $72, and $96 in 2020, 2019, and 2018, respectively.

The securities underlying the agreements have a carrying value and a fair value of $68,773 and $31,020 at December 31, 2020 and 2019, respectively. Such securities remain under our control. We may be required to provide additional collateral based on the fair value of underlying securities. Securities sold under repurchase agreements without stated maturity dates, federal funds purchased, and FRB Discount Window advances generally mature within one to four days from the transaction date. We had no FRB Discount Window advances for the years ended December 31, 2020 and 2019.

In the event of maturities, calls, significant principal repayments, or significant decline in market values, we have an adequate level of AFS securities available to pledge to satisfy required collateral. As of December 31, 2020, we had the ability to borrow up to an additional $214,625, based on assets pledged as collateral. We had no investment securities that were restricted to be pledged for specific purposes. Derivative Instruments We have entered into interest rate swaps to manage exposure to interest rate risk and variability in cash flows. The interest rate swaps, associated with our variable rate borrowings, are designated upon inception as cash flow hedges of forecasted interest payments. We have entered into LIBOR-based interest rate swaps that involve the receipt of variable amounts in exchange for fixed rate payments, in effect converting variable rate debt to fixed rate debt. Cash flow hedges are assessed for effectiveness using regression analysis. The effective portion of changes in fair value are recorded in OCI and subsequently reclassified into interest expense in the same period in which the related interest on the variable rate borrowings affects earnings. In the event that a portion of the changes in fair value were determined to be ineffective, the ineffective amount would be recorded in earnings. The following tables provide information on derivatives related to variable rate borrowings as of December 31: Pay Rate Receive Rate Remaining Life (Years) Notional Amount Balance Sheet Location Fair Value 2020 Derivatives designated as hedging instruments Cash Flow Hedges: Interest rate swaps 1.56 % 3-Month LIBOR 0.3 $ 10,000 Other liabilities $ (54) Pay Rate Receive Rate Remaining Life (Years) Notional Amount Balance Sheet Location Fair Value 2019 Derivatives designated as hedging instruments Cash Flow Hedges: Interest rate swaps 1.56 % 3-Month LIBOR 1.3 $ 10,000 Other assets $ 67 Derivatives contain an element of credit risk which arises from the possibility that we will incur a loss as a result of a counterparty failing to meet its contractual obligations. Credit risk is minimized through counterparty collateral, transaction limits and monitoring procedures. We also manage dealer credit risk by entering into interest rate derivatives only with primary and highly rated counterparties, the use of ISDA master agreements, and the use of counterparty limits. We do not anticipate any losses from failure of interest rate derivative counterparties to honor their obligations. 65 Table of Contents Note 10 – Off-Balance-Sheet Activities, Commitments and Other Matters Credit-Related Financial Instruments We are party to credit related financial instruments with off-balance-sheet risk. These financial instruments are entered into in the normal course of business to meet the financing needs of our customers. These financial instruments involve, to varying degrees, elements of credit and IRR in excess of the amounts recognized in the consolidated balance sheets. The contractual or notional amounts of these instruments reflect the extent of involvement we have in a particular class of financial instrument. The following table summarizes our credit related financial instruments with off-balance-sheet risk as of December 31: Unfunded commitments under lines of credit Commercial and standby letters of credit Commitments to grant loans Total 2020 2019 241,637 $ 5,964 26,939 274,540 $ 202,871 4,575 20,778 228,224 $ $ Unfunded commitments under lines of credit are commitments for possible future extensions of credit to existing customers. These commitments may expire without being drawn upon and do not necessarily represent future cash requirements. Advances to mortgage brokers are also included in unfunded commitments under lines of credit. The unfunded commitment amount is the difference between our outstanding balances and maximum outstanding aggregate amount. Commitments to grant loans are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. The amount of collateral obtained, if it is deemed necessary, is based on management's credit evaluation of the customer. Commitments to grant loans include residential mortgage loans that may be committed to be sold to the secondary market. Commercial and standby letters of credit are conditional commitments we issued to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support private borrowing arrangements, including commercial paper, bond financing, and similar transactions. These commitments to extend credit and letters of credit generally mature within one year. The credit risk involved in these transactions is essentially the same as that involved in extending loans to customers. We evaluate each customer’s credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary upon the extension of credit, is based on our credit evaluation of the borrower. While we consider standby letters of credit to be guarantees, the amount of the liability related to such guarantees on the commitment date is not significant and a liability related to such guarantees is not recorded on the consolidated balance sheets. Our exposure to credit-related loss in the event of nonperformance by the counter parties to the financial instruments for commitments to extend credit and standby letters of credit could be up to the contractual notional amount of those instruments. We use the same credit policies as we do for extending loans to customers. No significant losses are anticipated as a result of these commitments. Derivative Loan Commitments Mortgage loan commitments are referred to as derivative loan commitments if the loan that will result from exercise of the commitment will be held for sale upon funding. We enter into commitments to fund residential mortgage loans at specific times in the future, with the intention that these loans will subsequently be sold in the secondary market. A mortgage loan commitment binds us to lend funds to a potential borrower at a specified interest rate within a specified period of time, generally up to 60 days after inception of the rate lock. Outstanding derivative loan commitments expose us to the risk that the price of the loans arising from the exercise of the loan commitment might decline from the inception of the rate lock to funding of the loan due to increases in mortgage interest rates. If interest rates increase, the value of these loan commitments decreases. Conversely, if interest rates decrease, the value of these loan commitments increase. The notional amount of undesignated interest rate lock commitments was $3,557 and $618 at December 31, 2020 and 2019, respectively. Forward Loan Sale Commitments To protect against the price risk inherent in derivative loan commitments, we utilize both “mandatory delivery” and “best efforts” forward loan sale commitments to mitigate the risk of potential decreases in the values of loan that would result from the exercise of the derivative loan commitments. 66 Table of Contents With a “mandatory delivery” contract, we commit to deliver a certain principal amount of mortgage loans to an investor at a specified price on or before a specified date. If we fail to deliver the amount of mortgages necessary to fulfill the commitment by the specified date, we are obligated to pay a “pair-off” fee, based on then current market prices, to the investor to compensate the investor for the shortfall. With a “best efforts” contract, we commit to deliver an individual mortgage loan of a specified principal amount and quality to an investor if the loan to the underlying borrower closes. Generally, the price the investor will pay the seller for an individual loan is specified prior to the loan being funded (e.g. on the same day the lender commits to lend funds to a potential borrower). We expect that these forward loan sale commitments will experience changes in fair value opposite to the change in fair value of derivative loan commitments. The notional amount of undesignated forward loan sale commitments was $4,661 and $1,332 at December 31, 2020 and 2019, respectively. The fair value of these forward loan sale commitments was $4,778 and $1,353 at December 31, 2020 and 2019, respectively. The fair values of the rate lock loan commitments related to the origination of mortgage loans that will be held for sale and the forward loan sale commitments are deemed insignificant by management and, accordingly, are not recorded in our consolidated financial statements. Other Matters Banking regulations required us to maintain cash reserve balances in currency or deposits with the FRB until March of 2020 when reserve requirements were reduced to zero. At December 31, 2019 the reserve balance amounted to $1,341. Additionally, correspondent banks may require us to maintain minimum cash reserve balances. At December 31, 2020 and 2019, the reserve balances related to correspondent banks amounted to $500 and $400, respectively. Banking regulations limit the transfer of assets in the form of dividends, loans, or advances from the Bank to the Corporation. At December 31, 2020, substantially all of the Bank’s assets were restricted from transfer to the Corporation in the form of loans or advances. Bank dividends are the principal source of funds for the Corporation. Payment of dividends without regulatory approval is limited to the current year’s retained net income plus retained net income for the preceding two years, less any required transfers to common stock. At January 1, 2021, the amount available to the Corporation for dividends from the Bank, without regulatory approval, was approximately $16,100. Note 11 – Minimum Regulatory Capital Requirements The Corporation (on a consolidated basis) and the Bank are subject to various regulatory capital requirements administered by the FRB and the FDIC. Failure to meet minimum capital requirements can initiate mandatory and possibly additional discretionary actions by the FRB and the FDIC that, if undertaken, could have a material effect on our financial statements. Under regulatory capital adequacy guidelines and the regulatory framework for prompt corrective action, we must meet specific capital guidelines that include quantitative measures of assets, liabilities, capital, and certain off-balance-sheet items, as calculated under regulatory accounting standards. Our capital amounts and classifications are also subject to qualitative judgments by the FRB and the FDIC about components, risk weightings, and other factors. Prompt corrective action provisions are not applicable to bank holding companies. Quantitative measures established by regulation to ensure capital adequacy require us to maintain minimum amounts and ratios (set forth in the following table) of total capital, tier 1 capital, and common equity tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined) and tier 1 capital to average assets (as defined). We believe, as of December 31, 2020 and 2019, that we met all capital adequacy requirements. The FRB has established minimum risk-based capital guidelines. Pursuant to these guidelines, a framework has been established that assigns risk weights to each category of on and off-balance-sheet items to arrive at risk adjusted total assets. Regulatory capital is divided by the risk adjusted assets with the resulting ratio compared to the minimum standard to determine whether a corporation has adequate capital. The common equity tier 1 capital ratio has a minimum requirement of 4.50%. The minimum standard for primary, or Tier 1 capital is 6.00% and the minimum standard for total capital is 8.00%. 67 Table of Contents As of December 31, 2020 and 2019, the most recent notifications from the FRB and the FDIC categorized us as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, an institution must maintain total risk-based, Tier 1 risk-based, Common Equity Tier 1, and Tier 1 leverage ratios as set forth in the following tables. There were no conditions or events since the notifications that we believe have changed our categories. Our actual capital amounts and ratios are also presented in the table.

Diluted earnings per common share includes additional common shares that would have been outstanding if dilutive potential common shares had been issued. Potential common shares that may be issued relate solely to outstanding shares in the Directors Plan and grant awards under the RSP, see "Note 13 – Benefit Plans." Earnings per common share have been computed based on the following for the years ended December 31: Average number of common shares outstanding for basic calculation Average potential effect of common shares in the Directors Plan Average potential effect of common shares in the RSP Average number of common shares outstanding used to calculate diluted earnings per common share (1) Net income Earnings per common share Basic Diluted (1) Exclusive of shares held in the Rabbi Trust Note 13 – Benefit Plans 401(k) Plan 2020 2019 2018 7,959,705 143,878 2,508 7,909,794 185,248 — 8,106,091 8,095,042 10,885 $ 13,024 $ 1.37 $ 1.34 $ 1.65 $ 1.61 $ 7,872,077 200,771 — 8,072,848 14,021 1.78 1.74 $ $ $ We have a 401(k) plan in which substantially all employees are eligible to participate. Employees may contribute up to 100% of their compensation subject to certain limits based on federal tax laws. The plan was amended in 2013 to provide a matching safe harbor contribution for all eligible employees equal to 100% of the first 5.0% of an employee's compensation contributed to the Plan during the year. Employees are 100% vested in the safe harbor matching contributions. For 2020, 2019 and 2018, expenses attributable to the plan were $813, $764, and $743, respectively. Defined Benefit Pension Plan We maintain a noncontributory defined benefit pension plan, which was curtailed effective March 1, 2007. As a result of the curtailment, future salary increases are no longer considered (the projected benefit obligation is equal to the accumulated benefit obligation), and plan benefits are based on years of service and the individual employee’s five highest consecutive years of compensation out of the last ten years of service through March 1, 2007. 69 Table of Contents Changes in the projected benefit obligation and plan assets during each year, the funded status of the plan, and the net amount recognized in our consolidated balance sheets using an actuarial measurement date of December 31, are summarized as follows during the years ended December 31: Change in benefit obligation Benefit obligation, January 1 Interest cost Actuarial loss (gain) Benefits paid, including plan expenses Benefit obligation, December 31 Change in plan assets Fair value of plan assets, January 1 Investment return (loss) Contributions Benefits paid, including plan expenses Fair value of plan assets, December 31 Deficiency in funded status at December 31, included on the consolidated balance sheets in accrued interest payable and other liabilities Accumulated benefit obligation at December 31 Change in accrued pension benefit costs Accrued benefit cost at January 1 Contributions Net periodic benefit cost Net change in unrecognized actuarial loss and prior service cost Accrued pension benefit cost at December 31 2020 2019 10,209 $ 306 682 (839) 10,358 8,352 750 — (839) 8,263 (2,095) $ 10,358 $ 9,412 378 1,216 (797) 10,209 7,765 1,384 — (797) 8,352 (1,857) 10,209 2020 2019 (1,857) $ — (176) (62) (2,095) $ (1,647) — (268) 58 (1,857) $ $ $ $ $ We have recorded the funded status of the plan in our consolidated balance sheets. We adjust the underfunded status in a liability account to reflect the current funded status of the plan. Any gains or losses that arise during the year but are not recognized as components of net periodic benefit cost are recognized as a component of other comprehensive income (loss). The components of net periodic benefit cost are as follows for the years ended December 31: Interest cost on benefit obligation Expected return on plan assets Amortization of unrecognized actuarial net loss Settlement loss Net periodic benefit cost 2020 2019 2018 306 $ (488) 206 152 176 $ 378 $ (452) 214 128 268 $ 388 (554) 242 269 345 $ $ During 2020, 2019 and 2018, settlement losses of $152, $128 and $269 were recognized in connection with lump-sum benefit distributions, respectively. Many plan participants elect to receive their retirement benefit payments in the form of lump-sum settlements. Pro rata settlement losses, which can occasionally occur as a result of these lump-sum distributions, are recognized only in years when the total of such distributions exceed the sum of the service and interest expense components of net periodic benefit cost. Accumulated other comprehensive income at December 31, 2020 includes net unrecognized pension costs before income taxes of $3,474. 70 Table of Contents The actuarial assumptions used in determining the benefit obligation are as follows for the years ended December 31: Discount rate Expected long-term rate of return on plan assets 2020 2019 2018 2.30 % 6.00 % 3.07 % 6.00 % The actuarial weighted average assumptions used in determining the net periodic pension costs are as follows for the years ended December 31: Discount rate Expected long-term rate of return on plan assets 2020 2019 2018 3.07 % 6.00 % 4.11 % 6.00 % 4.11 % 6.00 % 3.48 % 6.00 % As a result of the curtailment of the Plan, there is no rate of compensation increase considered in the above assumptions. The expected long-term rate of return is an estimate of anticipated future long-term rates of return on plan assets as measured on a market value basis. Factors considered in arriving at this assumption include: • • • • Historical long-term rates of return for broad asset classes. Actual past rates of return achieved by the plan. The general mix of assets held by the plan. The stated investment policy for the plan. The selected rate of return is net of anticipated investment related expenses. Pension Plan Assets Our overall investment strategy is to moderately grow the portfolio by investing 50% of the portfolio in equity securities and 50% in fixed income securities. This strategy is designed to generate a long-term rate of return of 6.00%. Equity securities primarily consist of the S&P 500 Index with a smaller allocation to the Small Cap and International Index. Fixed income securities are invested in the Bond Market Index. The plan has appropriate assets invested in short-term investments to meet near term benefit payments. The asset mix and the sector weighting of the investments are determined by our benefits committee, which is comprised of members of our management. To manage the plan, we retain a third party investment advisor to conduct consultations. We review the performance of the advisor at least annually. The fair values of our pension plan assets by asset category were as follows as of December 31: Short-term investments Common collective trusts Fixed income Equity investments Total $ $ Total 2020 69 $ (Level 2) Total (Level 2) 2019 69 $ 218 $ 3,851 4,343 8,263 $ 3,851 4,343 8,263 $ 3,823 4,311 8,352 $ 218 3,823 4,311 8,352 The following is a description of the valuation methodologies used for assets measured at fair value. There have been no changes in the methodologies used at December 31, 2020 and 2019: • • Short-term investments: Shares of a money market portfolio valued at amortized cost, which approximates fair value. Common collective trusts: These investments are public investment securities valued using the NAV provided by a third party investment advisor. The NAV is quoted on a private market that is not active; however, the unit price is based on underlying investments which are traded on an active market. We anticipate contributions to the plan in 2021 to approximate net contribution costs. 71 Table of Contents Estimated future benefit payments are as follows for the next ten years: 2021 2022 2023 2024 2025 2026 - 2030 Directors Plan Estimated Benefit Payments 416 $ 422 421 416 426 2,322 Pursuant to the terms of the Directors Plan, our directors are required to invest at least 25% of their board fees in our common stock. These stock investments can be made either through deferred fees or through the purchase of shares through the Dividend Reinvestment Plan. Deferred fees, under the Directors Plan, are converted on a quarterly basis into stock units of our common stock based on the fair value of a share of our common stock as of the relevant valuation date. Stock units credited to a participant’s account are eligible for stock and cash dividends as declared. Dividend Reinvestment Plan shares are purchased pursuant to the Dividend Reinvestment Plan. Distribution of deferred fees from the Directors Plan occurs when the participant retires from the Board of Directors or upon the occurrence of certain other events. The participant is eligible to receive a distribution in the form of shares of our common stock of all of the stock units that are then in his or her account, and any unconverted cash will be converted to and rounded up to whole shares of stock and distributed, as well. The Directors Plan does not allow for cash settlement, and therefore, such share-based payment awards qualify for classification as equity. We may use authorized but unissued shares or purchase shares of common stock on the open market to meet our obligations under the Directors Plan. We maintain the Rabbi Trust to fund the Directors Plan. The Rabbi Trust is an irrevocable grantor trust to which we may contribute assets for the limited purpose of funding a nonqualified deferred compensation plan. Although we may not use the assets of the Rabbi Trust for any purpose other than meeting our obligations under the Directors Plan, the assets of the Rabbi Trust remain subject to the claims of our creditors and are included in the consolidated financial statements. We may contribute cash or common stock to the Rabbi Trust from time to time for the sole purpose of funding the Directors Plan. The Rabbi Trust will use any cash that we contribute to purchase shares of our common stock on the open market. Shares held in the Rabbi Trust are included in the calculation of earnings per share. The components of shares eligible to be issued under the Directors Plan were as follows as of December 31: Unissued Shares held in Rabbi Trust Total Cash Incentive Plans Executive Cash Incentive Plan 2020 2019 Eligible Shares Market Value Eligible Shares Market Value 117,053 $ 59,162 176,215 $ 2,291 1,158 3,449 177,935 $ 27,069 205,004 $ 4,326 658 4,984 On June 24, 2020, we amended and restated the Isabella Bank Corporation Employee Cash Incentive Plans to create two separate plans: one for non-executive employees and the other, the Isabella Bank Corporation Executive Cash Incentive Plan for executive employees. The executive plan provides separate potential payouts for Isabella Bank's CEO, President and CFO based on achievement of personal and corporate goals. The potential payouts under the plan range from 20% to 30% of the employee's annual salary. Expenses related to this plan for 2020 were $165. Employee Cash Incentive Plan We provide cash incentive plans to reward employees above and beyond their base salaries when our performance and operating profitability exceed established annual targets. Incentives are also awarded for achievement of personal performance 72 Table of Contents goals. Expenses related to this plan for 2020, 2019 and 2018 were $1,101, $1,070, and $500, respectively. Prior to 2020, such expenses included cash incentives for all eligible employees, including executives. Restricted Stock Plan On June 24, 2020 the Board of Directors adopted the RSP, an equity-based bonus plan. The primary purpose of the plan is to promote our growth and profitability by attracting and retaining executive officers and key employees of outstanding competence through ownership of equity that provides them with incentives to achieve corporate objectives. In connection with the adoption of the RSP, the Isabella Bank Corporation Stock Award Incentive Plan was terminated. The RSP authorizes the issuance of unvested restricted stock to an eligible employee with a maximum award ranging from 25% to 40% of the employee’s annual salary, on a calendar year basis. Under the RSP, the Board of Directors may grant restricted stock awards to eligible employees on an annual basis based on satisfactory achievement of performance targets and measures established by the Board of Directors. If these grant conditions are not satisfied, then the award of restricted shares will lapse or be adjusted appropriately, at the discretion of the Board of Directors. Restricted stock awards granted are not fully transferable or vested until certain conditions are met, as stated in the plan. Also on June 24, 2020 we made initial awards under the RSP. Currently, the eligible employees are Isabella Bank's CEO, President, and CFO. A summary of changes in nonvested restricted stock awards for the year follows: Balance, January 1, 2020 Granted Vested Forfeited Balance, December 31, 2020 Number of Shares Fair Value — $ 4,658 — — 4,658 $ — 82 — — 82 Compensation expense related to the RSP was $14 for 2020. As of December 31, 2020, there was $68 of total remaining unrecognized compensation expense related to nonvested restricted stock awards granted under the RSP. The remaining expense is expected to be recognized over a weighted-average service period of 3.17 years. Stock Award Incentive Plan We maintained an equity incentive plan for the purpose of promoting growth and operating profitability, as well as attracting and retaining executive officers of outstanding competence, through ownership of equity. Under this plan, stock was granted to specified individuals subject to certain conditions, and the transfer of shares granted under the plan is restricted. Expenses related to this plan for 2019 and 2018 were $171 and $45, respectively. This plan was terminated in 2020 with the adoption of our Restricted Stock Plan. Other Employee Benefit Plans We maintain nonqualified defined contribution retirement plans to provide supplemental retirement benefits to specified participants. Expenses related to these programs for 2020, 2019 and 2018 were $373, $355, and $356, respectively. Expenses are recognized over the participants’ expected years of service. We maintain a self-funded medical plan under which we are responsible for the first $75 per year of claims made by a covered family. Expenses are accrued based on estimates of the aggregate liability for claims incurred and our experience. Expenses were $1,868 in 2020, $2,445 in 2019 and $2,695 in 2018. 73 Table of Contents Note 14 – Revenue Our revenue is comprised primarily of interest income, service charges and fees, gains on the sale of loans and AFS securities, earnings on corporate owned life insurance policies, and other noninterest income. Other noninterest income is typically service and performance driven in nature and comprised primarily of investment and trust advisory fees. We recognize revenue, excluding interest income, in accordance with ASC 606, Revenue From Contracts with Customers. Revenue is recognized when our performance obligation has been satisfied according to our contractual obligation. We record receivables when revenue is unpaid and collectability is reasonably assured. Accounts receivable balances primarily represent amounts due from customers for which revenue has been recognized. Accounts receivable balances are recorded in the consolidated balance sheets in accrued interest receivable and other assets. For the years ended December 31, 2020, 2019 and 2018, we satisfied our performance obligations pursuant to contracts with customers. As a result, we have not recorded any contract assets or liabilities. We estimate no returns or allowances for the years ended December 31, 2020, 2019 and 2018. Our contracts with customers define our performance obligations with clearly established pricing which did not require us to allocate or disaggregate revenue by performance obligation. A summary of revenue recognized for each major category of contracts with customers, subject to ASC 606, is as follows for the years ended December 31: Debit card income Trust service fees Investment advisory fees Service charges and fees related to deposit accounts $ 2020 2019 2018 2,961 $ 2,294 284 290 2,667 $ 2,269 523 317 2,487 2,134 702 332 A significant portion of our revenue consists of interest income which is not subject to the requirements set forth in ASC 606.

As such, we did not record a deferred tax asset as of December 31, 2020 related to our investment in CSS. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for federal income tax purposes. Significant components of our deferred tax assets and liabilities, measured at the 21% statutory rate, included in other assets and other liabilities on our consolidated balance sheets, are summarized as follows as of December 31: Deferred tax assets Allowance for loan losses Deferred compensation Employee benefit plans Core deposit premium and acquisition expenses Net unrecognized actuarial losses on pension plan Net unrealized gains on derivative instruments Life insurance death benefit payable Other Total deferred tax assets Deferred tax liabilities Prepaid pension cost Premises and equipment Accretion on securities Core deposit premium and acquisition expenses Net unrealized gains on available-for-sale securities Net unrealized gains on derivative instruments Other Total deferred tax liabilities Net deferred tax assets (liabilities) 2020 2019 $ $ 1,724 $ 1,475 59 751 729 11 497 890 6,136 290 2,196 36 910 2,777 — 956 7,165 (1,029) $ 1,255 1,615 77 742 717 — 497 771 5,674 327 1,859 37 872 1,247 14 1,157 5,513 161 While we are subject to U.S. federal income tax, we are no longer subject to examination by taxing authorities for years before 2017. There are no material uncertain tax positions requiring recognition in our consolidated financial statements. We do not expect the total amount of unrecognized tax benefits to significantly increase in the next twelve months. We recognize interest and/or penalties related to income tax matters in income tax expense. We do not have any amounts accrued for interest and penalties at December 31, 2020 and 2019 and we are not aware of any claims for such amounts by federal income tax authorities. 75 Table of Contents Note 17 – Accumulated Other Comprehensive Income (Loss) AOCI includes net income as well as unrealized gains and losses, net of tax, on AFS securities and derivative instruments, as well as changes in the funded status of our defined benefit pension plan. Unrealized gains and losses and changes in the funded status of the pension plan, net of tax, are excluded from net income, and are reflected as a direct charge or credit to shareholders’ equity. Comprehensive income (loss) and the related components are disclosed in the consolidated statements of comprehensive income.

These levels are: Level 1: Level 2: Level 3: Valuation is based upon quoted prices for identical instruments traded in active markets. Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model based valuation techniques for which all significant assumptions are observable in the market. Valuation is generated from model based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability. The asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques maximize the use of observable inputs and minimize the use of unobservable inputs. Transfers between measurement levels are recognized at the end of reporting periods. Fair value measurement requires the use of an exit price notion which may differ from entrance pricing. Generally, we believe our assets and liabilities classified as Level 1 or Level 2 approximate an exit price notion. Following is a description of the valuation methodologies, key inputs, and an indication of the level of the fair value hierarchy in which the assets or liabilities are classified. AFS securities: AFS securities are recorded at fair value on a recurring basis. Level 1 fair value measurement is based upon quoted prices for identical instruments. Level 2 fair value measurement is based upon quoted prices for similar instruments. If quoted prices are not available, fair values are measured using independent pricing models or other model based valuation techniques such as the present value of future cash flows, adjusted for the security’s credit rating, prepayment assumptions and other factors such as credit loss and liquidity assumptions. The values for Level 1 and Level 2 investment securities are generally obtained from an independent third party. On a quarterly basis, we compare the values provided to alternative pricing sources. Loans: We do not record loans at fair value on a recurring basis. However, from time to time, loans are classified as impaired and a specific allowance for loan losses may be established. Loans for which it is probable that payment of interest and principal will be significantly different than the contractual terms of the original loan agreement are considered impaired. Once a loan is identified as impaired, we measure the estimated impairment. The fair value of impaired loans is estimated using one of several methods, including the present value of expected future cash flows discounted at the loan’s effective interest rate, or the fair value of the collateral, less costs to sell, if the loan is collateral dependent. Those impaired loans not requiring an allowance represent loans for which the fair value of the expected repayments or collateral exceed the recorded investments in such loans. We review the net realizable values of the underlying collateral for collateral dependent impaired loans on at least a quarterly basis for all loan types. To determine the collateral value, we utilize independent appraisals, broker price opinions, or internal evaluations. We review these valuations to determine whether an additional discount should be applied given the age of market information that may have been considered as well as other factors such as costs to sell an asset if it is determined that the collateral will be liquidated in connection with the ultimate settlement of the loan. We use these valuations to determine if any specific reserves or charge-offs are necessary. We may obtain new valuations in certain circumstances, including when there has been significant deterioration in the condition of the collateral, if the foreclosure process has begun, or if the existing valuation is deemed to be outdated. 78 Table of Contents The following tables list the quantitative fair value information about impaired loans as of: Valuation Technique Fair Value Discounted value $19,540 Valuation Technique Fair Value Discounted value $19,135 December 31, 2020 Unobservable Input Discount applied to collateral: Real Estate Equipment Cash crop inventory Livestock Other inventory Accounts receivable Liquor license December 31, 2019 Unobservable Input Discount applied to collateral: Real Estate Equipment Cash crop inventory Livestock Other inventory Accounts receivable Actual Range Weighted Average 20% - 30% 20% - 50% 40% 30% 50% 25% - 50% 75% 23% 32% 40% 30% 50% 27% 75% Actual Range Weighted Average 20% - 30% 20% - 40% 40% 30% 50% 25% - 50% 22% 32% 40% 30% 50% 28% Collateral discount rates may have ranges to accommodate differences in the age of the independent appraisal, broker price opinion, or internal evaluation. Derivative instruments: Derivative instruments, consisting solely of interest rate swaps, are recorded at fair value on a recurring basis. Derivatives qualifying as cash flow hedges, when highly effective, are reported at fair value in other assets or other liabilities on our Consolidated Balance Sheets with changes in value recorded in OCI. Should the hedge no longer be considered effective, the ineffective portion of the change in fair value is recorded directly in earnings in the period in which the change occurs. The fair value of a derivative is determined by quoted market prices and model-based valuation techniques. As such, we classify derivative instruments as Level 2. OMSR: OMSR (which are included in other assets) are subject to impairment testing. To test for impairment, we utilize a discounted cash flow analysis using interest rates and prepayment speed assumptions currently quoted for comparable instruments and discount rates. If the valuation model reflects a value less than the carrying value, OMSR are adjusted to fair value through a valuation allowance as determined by the model. As such, we classify OMSR subject to nonrecurring fair value adjustments as Level 2. Equity securities without readily determinable fair values: Equity securities without readily determinable fair values include our holdings in FHLB stock and FRB stock as well as our membership interest in CSS. As a 50% investor of the membership units in CSS, we accounted for our investment under the equity method of accounting. The General Manager of CSS, through the normal course of business, chose to evaluate its operations of the company and obtained an independent, third-party valuation of the company during the fourth quarter of 2019. As of December 31, 2019, our recorded investment in CSS relied on assumptions and use of estimates pursuant to the valuation. As such, we classify such equity securities instruments as Level 3 with the related impairment in 2019 a nonrecurring Level 3 fair value adjustment. We sold our membership interest in CSS during the fourth quarter of 2020. The preceding methods described may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Although we believe our valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement. 79 Table of Contents Estimated Fair Values of Financial Instruments Not Recorded at Fair Value in their Entirety on a Recurring Basis Disclosure of the estimated fair values of financial instruments, which differ from carrying values, often requires the use of estimates. In cases where quoted market values in an active market are not available, we use present value techniques and other valuation methods to estimate the fair values of our financial instruments. These valuation methods require considerable judgment and the resulting estimates of fair value can be significantly affected by the assumptions made and methods used. The carrying amount and estimated fair value of financial instruments not recorded at fair value in their entirety on a recurring basis were as follows as of December 31: ASSETS Cash and cash equivalents Mortgage loans AFS Gross loans Less allowance for loan and lease losses Net loans Accrued interest receivable Equity securities without readily determinable fair values (1) OMSR LIABILITIES Deposits without stated maturities Deposits with stated maturities Borrowed funds Accrued interest payable ASSETS Cash and cash equivalents Mortgage loans AFS Gross loans Less allowance for loan and lease losses Net loans Accrued interest receivable Equity securities without readily determinable fair values (1) OMSR LIABILITIES Deposits without stated maturities Deposits with stated maturities Borrowed funds Accrued interest payable Carrying Value Estimated Fair Value 2020 Level 1 Level 2 Level 3 $ $ 246,640 $ 2,741 1,238,311 9,744 1,228,567 6,882 17,383 2,308 1,183,336 382,981 158,747 481 246,640 $ 2,858 1,239,718 9,744 1,229,974 6,882 N/A 2,480 1,183,336 389,455 160,250 481 Carrying Value Estimated Fair Value 60,572 $ 904 1,186,570 7,939 1,178,631 6,501 60,572 $ 925 1,170,370 7,939 1,162,431 6,501 21,629 2,264 906,232 407,619 275,999 860 N/A 2,264 906,232 409,600 278,761 860 246,640 $ — — — — 6,882 — — 1,183,336 — — 481 2019 Level 1 60,572 $ — — — — 6,501 — — 906,232 — — 860 — $ 2,858 — — — — — 2,480 — 389,455 160,250 — — — 1,239,718 9,744 1,229,974 — — — — — — — Level 2 Level 3 — $ 925 — — — — — 2,264 — 409,600 278,761 — — — 1,170,370 7,939 1,162,431 — — — — — — — (1) Due to the characteristics of equity securities without readily determinable fair values, they are not disclosed under a specific fair value hierarchy.

The transaction is expected to produce future benefits for us in the form of reduced operational costs and better-managed risk. Assets and liabilities transferred from the parent company to the Bank related primarily to capital assets, net deferred income tax asset, prepaid assets, employee benefits payable, accrued expenses, and a pension plan. Effective January 1, 2019, employee compensation and benefit expenses are now recognized directly by the Bank, where expenses related to certain administrative functions were previously recognized by the parent holding company. Similarly, expenses related to most capital assets are now recognized directly by the Bank. A portion of employee compensation and benefit expenses, as well as some expenses related to capital assets, are now recognized by the holding company through a management fee paid to the Bank. 84 Table of Contents Item 9. Changes in and Disagreements With Accountants on Accounting and Financial Disclosure. None. Item 9A. Controls and Procedures. DISCLOSURE CONTROLS AND PROCEDURES We carried out an evaluation, under the supervision and with the participation of the Principal Executive Officer and Principal Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15(d)-15(e) under the Exchange Act) as of December 31, 2020, pursuant to Exchange Act Rule 13a-15. Based upon that evaluation, the Principal Executive Officer and Principal Financial Officer concluded that our disclosure controls and procedures as of December 31, 2020, were effective to ensure that information required to be disclosed in reports that we file or submit under the Exchange Act are recorded, processed, summarized and reported within the time periods specified in SEC rules and forms. CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING We also conducted an evaluation of internal control over financial reporting to determine whether any changes occurred during the quarter ended December 31, 2020, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. Based on this evaluation, we have concluded that there have been no such changes during the quarter ended December 31, 2020. Management’s Report on Internal Control Over Financial Reporting We are responsible for the preparation and integrity of our published consolidated financial statements. The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America and, accordingly, include amounts based on judgments and estimates. We also prepared the other information included in the Annual Report on Form 10-K and are responsible for the accuracy and consistency with the consolidated financial statements. We are responsible for establishing and maintaining a system of internal control over financial reporting, which is intended to provide reasonable assurance to our management and Board of Directors regarding the reliability of our consolidated financial statements. The system includes but is not limited to: • • • • • • A documented organizational structure and division of responsibility; Established policies and procedures, including a code of conduct to foster a strong ethical climate which is communicated throughout our Corporation; Internal auditors that monitor the operation of the internal control system and report findings and recommendations to management and the Audit Committee; Procedures for taking action in response to an internal audit finding or recommendation; Regular reviews of our consolidated financial statements by qualified individuals; and The careful selection, training and development of our people. There are inherent limitations in the effectiveness of any system of internal control, including the possibility of human error and the circumvention or overriding of controls. Also, the effectiveness of an internal control system may change over time. We have implemented a system of internal control that was designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for external purposes in accordance with generally accepted accounting principles. We have assessed our internal control system in relation to criteria for effective internal control over financial reporting described in “Internal Control-Integrated Framework” issued by the Committee of Sponsoring Organizations (2013 framework) of the Treadway Commission. Based upon these criteria, we believe that, as of December 31, 2020, our system of internal control over financial reporting was effective. Our independent registered public accounting firm, Rehmann Robson LLC ("Rehmann"), has audited our 2020 consolidated financial statements and our internal control over financial reporting as of December 31, 2020. Rehmann was given unrestricted access to all financial records and related data, including minutes of all meetings of stockholders, the Board of Directors and committees of the Board of Directors. Rehmann has issued an unqualified audit opinion on our 2020 85 Table of Contents consolidated financial statements and an unqualified opinion on the effectiveness of our internal controls as of December 31, 2020, as a result of the integrated audit.

We have adopted a Code of Conduct and Business Ethics that applies to the principal executive officer, the principal financial officer and the principal accounting officer or controller of the Corporation. We shall provide to any person without charge upon request, a copy of our Code of Conduct and Business Ethics. Written requests should be sent to: Secretary, Isabella Bank Corporation, 401 North Main Street, Mount Pleasant, Michigan 48858. Item 11. Executive Compensation. For information concerning executive compensation, see “Executive Officers” and “Remuneration of Directors” in the Proxy Statement which is incorporated herein by reference. Item 12. Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters. For information concerning the security ownership of certain owners and management, see “Security Ownership of Certain Beneficial Owners and Management” in the Proxy Statement which is incorporated herein by reference. Equity Compensation Plan Information The following table provides information as of December 31, 2020, with respect to compensation plans under which our common shares are authorized for issuance to directors, officers or employees in exchange for consideration in the form of goods or services. Plan Category Equity compensation plans approved by shareholders: None Equity compensation plans not approved by shareholders: Deferred director compensation plan Restricted Stock Plan (2) (1) Total Number of Securities to be Issued Upon Exercise of Outstanding Options, Warrants, and Rights (A) — 117,053 (3) 18,704 (4) 135,757 Weighted Average Exercise Price of Outstanding Options, Warrants, and Rights (B) — — (5) — (5) Number of Securities Remaining Available for Future Issuance Under Equity Compensation Plans (Excluding Securities Reflected in Column (A)) (C) — — — (6) (6) (1) Pursuant to the terms of the Directors Plan, our directors are required to invest at least 25% of their board fees in our common stock. These stock investments can be made either through deferred fees or through the purchase of shares through the Dividend Reinvestment Plan. Deferred fees, under the Directors Plan, are converted on a quarterly basis into stock units of our common stock based on the fair value of a share of our common stock as of the relevant valuation date. Stock units credited to a participant’s account are eligible for stock and cash dividends as declared. Dividend Reinvestment Plan shares are purchased pursuant to the Dividend Reinvestment Plan. Distribution of deferred fees from the Directors Plan occurs when the participant retires from the Board of Directors or upon the occurrence of certain other events. The participant is eligible to receive a distribution in the form of shares of our common stock of all of the stock units that are then in his or her account, and any unconverted cash will be converted to and rounded up to whole shares of stock and distributed, as well. The Directors Plan does not allow for cash settlement, and therefore, such share-based payment awards qualify for classification as equity. We may use authorized but unissued shares or purchase shares of common stock on the open market to meet our obligations under the Directors Plan. (2) The RSP is an equity-based bonus plan. Under the plan, we may award restricted stock bonuses to eligible employees on an annual basis that are not fully transferable. Currently, the eligible employees are Isabella Bank's CEO, President, and CFO. 87 Table of Contents The RSP authorizes the issuance of unvested restricted stock to an eligible employee with a maximum award ranging from 25% to 40% of the employee’s annual salary, on a calendar year basis. The employee must also satisfy the annual performance targets and measures established by the Board of Directors. If these grant conditions are not satisfied, then the award of restricted shares will lapse or be adjusted appropriately, at the discretion of the Board of Directors. Awards are converted to shares upon payment to the participant based on the market value of our common stock on the date of award. (3) As of December 31, 2020, the Directors Plan had 176,215 shares eligible to be distributed under the Directors Plan. The Rabbi Trust holds 59,162 shares for the benefit of participants pursuant to the Directors Plan. Accordingly, such shares are not included in the number of securities issuable in column (A). (4) This amount includes shares subject to outstanding stock awards at the maximum amount of shares issuable under such awards. However, payout of incentive awards is contingent on the individual and the Corporation reaching certain levels of performance. If the performance criteria for these awards are not fully satisfied, the award recipient will receive less than the maximum number of shares eligible under these grants and may receive nothing from these grants. Additionally, this amount assumes the closing price of our common stock as of the award grant date, June 24, 2020, for purposes of the conversion from awards to stock. (5) (6) The Directors Plan and the RSP do not have an exercise price. There is no maximum number of shares available for issuance under the Directors Plan and the RSP has a maximum number of 100,000 shares. Item 13. Certain Relationships and Related Transactions, and Director Independence.
