Cautionary note regarding forward-looking statements This presentation contains forward-looking statements, which are any statements or information that are not historical facts. These forward-looking statements include statements about our anticipated future revenue and expenses and our future plans and prospects. Forward-looking statements involve inherent risks and uncertainties, and important factors could cause actual results to differ materially from those anticipated. For example, deterioration in general business and economic conditions or turbulence in domestic or global financial markets could adversely affect our revenues and the values of our assets and liabilities, reduce the availability of funding to us, lead to a tightening of credit, and increase stock price volatility. Our results could also be adversely affected by changes in interest rates; increases in unemployment rates; deterioration in the credit quality of our loan portfolios or in the value of the collateral securing those loans; deterioration in the value of our investment securities; legal and regulatory developments; changes in customer behavior and preferences; breaches in data security; and management's ability to effectively manage the multitude of risks facing our business. Key risk factors that could affect our future results are described in more detail in our Annual Report on Form 10-K for the year ended December 31, 2025 and the other reports we file with the SEC, including under the heading "Risk Factors." Investors should not place undue reliance on forward-looking statements as a prediction of our future results. Any forward-looking statement speaks only as of the date on which it is made, and we undertake no obligation to update any forward-looking statement, whether as a result of new information, future events, or otherwise. Additional Information and Where to Find It In connection with the proposed acquisition of HCB, we expect to file with the SEC a registration statement on Form S-4 that will include a preliminary proxy statement of HCB and a preliminary prospectus of Independent Bank Corporation. Shareholders are urged to read the proxy statement/prospectus when it becomes available because it will contain important information about the proposed transaction. Free copies of these documents, when available, may be obtained at the SEC's website (www.sec.gov) or upon written request to Independent Bank Corporation, 4200 East Beltline, Grand Rapids, MI 49525, Attention: Investor Relations, or HCB Financial Corp., 150 West Court Street, Hastings, MI 49058, Attention: Amanda Belcher-Currier, CFO. A final proxy statement/prospectus will be mailed to the shareholders of HCB. No Offer or Solicitation This presentation is not an offer to sell or the solicitation of an offer to buy any securities, or a solicitation of any vote or approval, nor shall there be any sale of securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of such jurisdiction. 2 2

Earning asset expansion is centered in commercial loans up $54 million and overnight liquidity, up $40 million. Runoff in lower yielding investments and consumer loans helped fund earning asset growth. Asset and liability yields were stable during the quarter, with asset yields up 2 basis points and liability costs 1 basis point higher. • The NII sensitivity position to lower rates declined modestly while the benefit to higher rates remained largely unchanged. Reduced exposure to lower rates is due to $75 million notional of floor purchases, termination of $87 million of short term pay fixed swaps and a slight shortening in the maturity structure of time deposits. The overall position is closely matched for smaller rate changes of +/- 100 basis points. The bank has modest exposure to larger rate declines and benefits from larger rate increases. • Base-rate is a static balance sheet applying the spot yield curve from the valuation date. • Stable core funding base. Transaction accounts fund 38.4% of assets and other non-maturity deposits fund another 17.4% of assets. Low wholesale funding of just 2.2% of assets. • 38.2% of assets reprice in 1 month and 49.3% reprice in the next 12 months. • Continually evaluating strategies to manage NII through hedging, funding strategies as well as product pricing and structure. Changes in Net Interest Income (Dollars in 000's) Simulation analyses calculate the change in net interest income over the next twelve months, under immediate parallel shifts in interest rates, based upon a static statement of financial condition, which includes derivative instruments, and does not consider loan fees. 35

Outlook for 2026 Outlook for 2026 \*as of January, 2026 • IBCP forecast of approximately 4.5%-5.5% overall loan growth is based on an increase in commercial loans (11%-12%) with mortgage loans (0%-1%) and installment loans declining (5.0%-5.5%). • This growth forecast also assumes a stable Michigan economy. • The forecast assumes 0.25% Fed rate cuts in March and August in the federal funds rate while long-term interest rates increase slightly over year-end 2025 levels. • IBCP forecast of high-single digit (7%-8%) growth is primarily supported by an increase in earning assets and a favorable shift in the earning asset base. Expect the net interest margin (NIM) to increase (0.18% - 0.23%) in 2026 compared to full-year 2025. Primary driver is a decrease in yield on interest bearing liabilities that is partially offset by a decrease in earning asset yield. • Very difficult area to forecast. Future provision levels under CECL will be particularly sensitive to loan growth and mix, projected economic conditions, watch credit levels and loan default volumes. • The allowance as a percentage of total loans was at 1.48% at 12/31/25 • A full year 2026 provision (expense) for credit losses of approximately 0.20%-0.25% of average total portfolio loans would not be unreasonable. 1Q'26 Update • Total portfolio loans increased $31.8 million (3.0% annualized) in 1Q'26 which is below our forecasted range. Commercial loan growth of $53.8 million (9.9% annualized), mortgage loan decrease of $4.5 million (-1.2% annualized) and installment loan decrease of $17.5 million (-13.2% annualized). • 1Q'26 net interest income was $3.2 million (7.3%) higher than the prior year quarter which is within the forecasted range. The net interest margin was 3.65% for the current quarter and 3.49% for the prior year quarter and up 0.03% from the linked quarter. • The provision for credit losses was an expense of $0.4 million (0.03% annualized) for the first quarter below the forecasted range.

Outlook for 2026 Outlook for 2026 \*as of January, 2026 • Quarterly 2026 forecasted range of $11.3M to $12.3M. Full year up 3.0% to 4.0% from 2025 actual of $45.6M • Expect mortgage loan origination volumes to be down 6.0% to 7.0% and net gain on sale to be down 14.0% to 16.0% compared to full year 2025. Assumes mortgage loan servicing net of approximately $0.5M per quarter in 2026. • IBCP forecasts 2026 quarterly range of $36.0M to $37.0M with the total for the year up 5.0% to 6.0% from the 2025 actual of $138.2M. • The primary driver is an increase in compensation and employee benefits, data processing; loan and collections and occupancy. • Approximately a 17% effective income tax rate in 2026.This assumes a 21% statutory federal corporate income tax rate during 2026. • 2026 share repurchase authorization at approximately 5% (1.1 million) of outstanding shares. • Share repurchases will be dependent on capital levels, capital allocation options and share price trends. We are not modeling any share repurchases in 2026. 1Q'26 Update • Non-interest income totaled $12.0 million in 1Q'26, which is within the forecasted range. Mortgage loan originations increased $22.8 million over the prior year quarter while net gain as percentage of mortgages loans sold was 1.23% below the prior year quarter. • Total non-interest expense was $38.3 million in the 1Q'26, which was higher than our forecasted quarterly range. Non-recurring expense items include $1.5 million in litigation expense and $0.4 million true up related to promotional payments to deposit customers. • Actual effective income tax rate of 16.6% for the first quarter of 2026. • There were no shares of common stock repurchased in the first quarter of 2026.
