INDEPENDENT BANK CORPORATION REPORTS 2025 SECOND QUARTER RESULTS

Second Quarter Highlights

Highlights for the second quarter of 2025 include:

•Increase in net interest income of $0.9 million (or 2.1% ) over the first quarter of 2025;

•Increase in tangible common equity per share of common stock of $0.36 (or 6.9% annualized) from March 31, 2025;

•Net interest margin expansion of nine basis points compared to March 31, 2025;

•Net growth in loans of $91.7 million (or 9.0% annualized) from March 31, 2025; and

•The payment of a 26 cent per share dividend on common stock on May 15, 2025.

GRAND RAPIDS, Mich., July 24, 2025 - Independent Bank Corporation (NASDAQ: IBCP) reported second quarter 2025 net income of $16.9 million, or $0.81 per diluted share, versus net income of $18.5 million, or $0.88 per diluted share, in the prior-year period.

William B. (“Brad”) Kessel, the President and Chief Executive Officer of Independent Bank Corporation, commented: "I am proud of our team and pleased to see us continue our positive trends with our second quarter 2025 results. Overall, loans increased by 9.0% (annualized), while core deposits were down by 1.4% (annualized) due to seasonality. We generated net interest income growth on both a linked quarter basis and a year-over-year quarterly basis, producing nine basis points of margin expansion from the prior quarter. We believe our expenses are well managed, and we continue to see improved operational scale from strategic investments made in recent years. These fundamentals drove positive growth in tangible common equity per share of common stock (10.8%) compared to the prior year quarter, along with very healthy performance returns: a return on average assets of 1.27% and a return on average equity of 14.66%. Despite heightened uncertainty in the markets during the quarter, our credit metrics remain strong, with low levels of watch credits, 16 basis points of non-performing assets to total assets, and 0.02% net charge-offs to average loans of the quarter (annualized). The allowance for credit losses was 1.47% of total loans. Our team has been effective in many areas during the first half of 2025, including business development from the existing customer base and onboarding new relationships which have enhanced the geographic and product line diversification of our business. We continue to succeed in recruiting talented

bankers to join the Independent Bank team. During the second quarter, we rolled out several new technologies to make banking easier for both our customers and associates serving our customers. For all these reasons, I am optimistic about our prospects for growth in the balance of 2025 and 2026."

Significant items impacting comparable second quarter 2025 and 2024 results include the following:

•Changes in the fair value due to price of capitalized mortgage loan servicing rights (the “MSR Changes”) of $(0.2) million ($(0.01) per diluted share, after taxes) for the three-month period ended June 30, 2025, as compared to $0.9 million ($0.03 per diluted share, after taxes) for the three-month period ended June 30, 2024.

•Gain on equity securities at fair value of $2.7 million ($0.10 per diluted share, after tax) in the second quarter ended June 30, 2024, attributable to the exchange of our Visa Class B-1 common stock. No gain or loss on equity securities at fair value was recorded for the second quarter of 2025.

Operating Results

The Company’s net interest income totaled $44.6 million during the second quarter of 2025, an increase of $3.3 million, or 7.9% from the year-ago period, and an increase of $0.9 million, or 2.1%, from the first quarter of 2025. The Company’s tax equivalent net interest income as a percent of average interest-earning assets (the “net interest margin”) was 3.58% during the second quarter of 2025, compared to 3.40% in the year-ago period, and 3.49% in the first quarter of 2025. The year-over-year quarterly increase in net interest income was due to both an increase in average interest-earning assets and the higher net interest margin. The linked quarter increase in net interest income was due to an increase in the net interest margin that was partially offset by a decrease in average interest-earning assets. Average interest-earning assets were $5.04 billion in the second quarter of 2025, compared to $4.89 billion in the year ago quarter and $5.08 billion in the first quarter of 2025.

Non-interest income totaled $11.3 million for the second quarter of 2025, compared to $15.2 million in the comparable prior year period. This change was primarily due to a gain on equity securities at fair value of $2.7 million in the prior year quarter as well as variances in mortgage banking related revenues.

Net gains on mortgage loans in the second quarters of 2025 and 2024 were approximately $1.6 million and $1.3 million, respectively. The comparative quarterly increase in net gains on mortgage loans was due to an increase in both gain on sale margin on mortgage loans sold and an increase in the volume of mortgage loans sold.

Mortgage loan servicing, net, generated income of $0.5 million and $2.1 million in the second quarters of 2025 and 2024, respectively. The significant variance in mortgage loan servicing, net is primarily due to changes in the fair value of capitalized mortgage loan servicing rights associated with changes in interest rates and the associated expected future prepayment levels and expected float rates as well as a decline in servicing revenue. The decline in servicing revenue is attributed to the sale of approximately $931 million of mortgage servicing rights on January 31, 2025. Capitalized mortgage loan servicing rights totaled $32.1 million and $46.8 million at June 30, 2025 and December 31, 2024, respectively. The decline during the first half of 2025 was primarily attributed to the aforementioned mortgage servicing right sale. This transaction was executed in part to reduce the amount of exposure the bank had to rate variances that may

impact the mortgage servicing right asset valuation in future periods. While the magnitude of fair value adjustments would also be expected to decrease, those adjustments are dependent upon factors that are harder to predict.

Mortgage loan servicing, net activity is summarized in the following table:


	Three months ended				Six months ended
	6/30/2025		6/30/2024		6/30/2025		6/30/2024
	(In thousands)
Mortgage loan servicing, net:

Fair value change due to pay-downs	(862)		(1,034)		(1,753)		(1,793)
Loss on sale of originated servicing rights	$	(78)	$	—	(172)		—
Total	$	490	$	2,091	$	(146)	$	4,816

Non-interest expenses totaled $33.8 million in the second quarter of 2025, compared to $33.3 million in the year-ago period.

The Company recorded income tax expense of $3.8 million in the second quarter of 2025. This compares to an income tax expense of $4.6 million in the second quarter of 2024. The change in income tax expense principally reflects changes in pre-tax earnings in 2025 relative to 2024.

Asset Quality

A breakdown of non-performing loans by loan type is as follows (1):


	6/30/2025			12/31/2024			6/30/2024

Ratio of non-performing loans to total portfolio loans	0.20		%	0.15		%	0.12		%
Ratio of non-performing assets to total assets	0.16		%	0.13		%	0.10		%
Ratio of allowance for credit losses to total non-performing loans	745.45		%	989.32		%	1253.98		%

(1) Non performing loans include non-accrual loans and loans 90 days or more past due and still accruing interest.

The provision for credit losses was an expense of $1.50 million and $0.02 million in the second quarters of 2025 and 2024, respectively. We recorded loan net charge offs of $0.37 million and $0.09 million in the second quarters of 2025 and 2024, respectively. At June 30, 2025, the allowance for credit losses for loans totaled $61.2 million, or 1.47% of total portfolio loans compared to $59.4 million, or 1.47% of total portfolio loans at December 31, 2024.

Balance Sheet, Capital and Liquidity

Total assets were $5.42 billion at June 30, 2025, an increase of $80.4 million from December 31, 2024. Loans, excluding loans held for sale, were $4.16 billion at June 30, 2025, compared to $4.04 billion at December 31, 2024. Deposits totaled $4.66 billion at June 30, 2025, an increase of $5.3 million from December 31, 2024. This increase is primarily due to increases in reciprocal and brokered time deposits that were partially offset by decreases in non-interest bearing, savings and interest-bearing checking and time deposits.

Cash and cash equivalents totaled $146.2 million at June 30, 2025, versus $119.9 million at December 31, 2024. Securities available for sale (“AFS”) totaled $509.5 million at June 30, 2025, versus $559.2 million at December 31, 2024.

Total shareholders’ equity was $469.3 million at June 30, 2025, or 8.66% of total assets compared to $454.7 million or 8.52% at December 31, 2024. Tangible common equity totaled $439.7 million at June 30, 2025, or $21.23 per share

compared to $424.9 million or $20.33 per share at December 31, 2024. The increase in shareholders’ equity as well as tangible common equity are primarily the result of earnings retention.

The Company’s wholly owned subsidiary, Independent Bank, remains significantly above “well capitalized” for regulatory purposes with the following ratios:


Regulatory Capital Ratios	6/30/2025		12/31/2024		Well Capitalized Minimum

Tier 1 capital to average total assets	9.79	%	9.58	%	5.00	%
Common equity tier 1 capital to risk-weighted assets	11.90	%	11.74	%	6.50	%
Tier 1 capital to risk-weighted assets	11.90	%	11.74	%	8.00	%
Total capital to risk-weighted assets	13.15	%	12.99	%	10.00	%

At June 30, 2025, in addition to liquidity available from our normal operating, funding, and investing activities, we had unused credit lines with the FHLB and FRB of approximately $1.02 billion and $484.6 million, respectively. We also had approximately $486.0 million in fair value of unpledged securities AFS and HTM at June 30, 2025 which could be pledged for an estimated additional borrowing capacity at the FHLB and FRB of approximately $455.9 million.

Share Repurchase Plan

On December 17, 2024, the Board of Directors of the Company authorized the 2025 share repurchase plan. Under the terms of the 2025 share repurchase plan, the Company is authorized to purchase up to 1,100,000 shares, or approximately 5% of its then outstanding common stock. The repurchase plan is authorized to last through December 31, 2025.

Reconciliation of Non-GAAP Financial Measures

Independent Bank Corporation

Independent Bank Corporation believes non-GAAP measures are meaningful because they reflect adjustments commonly made by management, investors, regulators and analysts to evaluate the adequacy of common equity and performance trends. Tangible common equity is used by the Company to measure the quality of capital.

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, 2024 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. 2 2

Asset yields were augmented by a shift in asset mix with good commercial loan growth partially funded by runoff of lower yielding investments. Also, assets continued to reprice higher. This benefit was partially offset by an adverse shift in funding mix with an increase in wholesale funding to finance earning asset growth and modest core deposit runoff. • The NII sensitivity position shows slightly more exposure to a declining rate environment. Asset repricing increased due to strong growth in variable rate commercial loans and HELOCs. Some of the increase in asset repricing was offset by purchased floors and faster liability repricing given an increase in short duration wholesale funding. • Base-rate is a static balance sheet applying the spot yield curve from the valuation date. • Stable core funding base. Transaction accounts fund 36.9% of assets and other non- maturity deposits fund another 18.4% of assets. Low wholesale funding of just 5.6% of assets. • 37.1% of assets reprice in 1 month and 49.2% 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. 13

The decrease in servicing revenue is attributed to the sale of approximately $931 million of mortgage servicing rights on January 31, 2025. • Mortgage banking: − $1.6 million in net gains on mortgage loans in 2Q'25 vs. $1.3 million in the year ago quarter. The increase is primarily due to higher profit margins on mortgage loan sales as well as higher loan sales volume. − $147.8 million in mortgage loan originations in 2Q'25 vs. $142.6 million in 2Q’24 and $107.8 million in 1Q'25. − 2Q'25 mortgage loan servicing includes a $0.2 million ($(0.01) per diluted share, after tax) decrease in fair value adjustment due to price compared to an increase of $0.9 million ($0.03 per diluted share, after tax) in the year ago quarter.

Outlook for 2025 Outlook for 2025 *as of January, 2025 • IBCP forecast of mid-single digit (approximately 5%-6%) overall loan growth is based on increases in commercial loans (9%-10%) and mortgage loans (2%-3%) with installment loans declining (2%-3%). • 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 2024 levels. • IBCP forecast of high-single digit (8%-9%) 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 (0.20% - 0.25%) in 2025 compared to full-year 2024. 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 1.47% at 12/31/24 • A full year 2025 provision (expense) for credit losses of approximately 0.15%-0.20% of average total portfolio loans would not be unreasonable. 2Q’25 Update • Total portfolio loans increased $91.7 million (9.0% annualized) in 2Q'25 which is above our forecasted range. Commercial loan growth of $75.9 million (15.3% annualized), mortgage loan growth of $15.6 million (4.1% annualized) and installment loan growth of $0.2 million (0.2% annualized). • 2Q'25 net interest income was $3.3 million (7.9%) higher than the prior year quarter which is within the forecasted range. The net interest margin was 3.58% for the current quarter and 3.40% for the prior year quarter and up 0.09% from the linked quarter. • The provision for credit losses was an expense of $1.5 million for the second quarter within the forecasted range. LENDING Continued growth NET INTEREST INCOME Growth driven primarily by higher average earning assets PROVISION FOR CREDIT LOSSES Steady asset quality metrics 16
