INDEPENDENT BANK CORPORATION REPORTS 2023 FOURTH QUARTER RESULTS

Fourth Quarter Highlights

Highlights for the fourth quarter of 2023 include:

•An increase in net interest income of $0.7 million (1.7%) over the third quarter of 2023;

•An increase in book value and tangible book value per share of $1.42 and $1.43 respectively;

•Net growth in loans of $49.4 million (or 5.2% annualized) from September 30, 2023; and

•The payment of a 23 cent per share dividend on common stock on November 13, 2023.

GRAND RAPIDS, Mich., January 25, 2024 - Independent Bank Corporation (NASDAQ: IBCP) reported fourth quarter 2023 net income of $13.7 million, or $0.65 per diluted share, versus net income of $15.1 million, or $0.71 per diluted share, in the prior-year period. For the year ended December 31, 2023, the Company reported net income of $59.1 million, or $2.79 per diluted share, compared to net income of $63.4 million, or $2.97 per diluted share, in 2022.

William B. (“Brad”) Kessel, the President and Chief Executive Officer of Independent Bank Corporation, commented: “'Our fourth quarter performance capped off another remarkably strong year, with our organization performing exceptionally well despite continued challenges in the macroeconomic environment. For the fourth quarter of 2023, I am particularly pleased with the double digit annualized growth in our commercial loan portfolio, the year over year 4.1% growth in our core deposit base, the linked quarter growth in our net interest income and our strong asset quality metrics which enabled us to release a small amount of loan loss reserves. Significantly impacting our quarterly results was the change in price of the fair value of our capitalized mortgage servicing rights of $3.6 million ($0.14 per diluted share, after tax). Adding back this non-cash adjustment, our fourth quarter 2023 annualized return on assets was 1.26% versus 1.24% for the three months ended December 31, 2022. During 2023, we continued to make investments in talent and technology which we believe will enable us to consistently add new customers, grow our market share, generate profitable growth, and further increase the value of our franchise in 2024 and beyond.”

Significant items impacting comparable 2023 and 2022 results include the following:

•Changes in the fair value due to price of capitalized mortgage loan servicing rights (the “MSR Changes”) of $(3.6) million ($(0.14) per diluted share, after taxes) and $(0.3) million ($(0.01) per diluted share, after taxes)

for the three-month and full-year ended December 31, 2023, respectively, as compared to $(0.5) million ($(0.02) per diluted share, after taxes) and $14.3 million ($0.53 per diluted share, after taxes) for the three-months and full-year ended December 31, 2022, respectively.

•The provision for credit losses was a credit of $0.6 million ($0.02 per diluted share, after taxes) and expense of $6.2 million ($0.23 per diluted share, after tax) in the fourth quarter and full year ended December 31, 2023, respectively, as compared to an expense of $1.4 million ($0.05 per diluted share, after taxes) and expense of $5.3 million ($0.20 per diluted share, after tax) in the fourth quarter and full year ended December 31, 2022, respectively.

Operating Results

The Company’s net interest income totaled $40.1 million during the fourth quarter of 2023, a decrease of $0.5 million, or 1.2% from the year-ago period, and up $0.7 million, or 1.7%, from the third quarter of 2023. The Company’s tax equivalent net interest income as a percent of average interest-earning assets (the “net interest margin”) was 3.26% during the fourth quarter of 2023, compared to 3.52% in the year-ago period, and 3.23% in the third quarter of 2023. The year-over-year quarterly decrease in net interest income was due to a decrease in the net interest margin that was partially offset by an increase in average earnings assets. Average interest-earning assets were $4.93 billion in the fourth quarter of 2023, compared to $4.64 billion in the year ago quarter and $4.89 billion in the third quarter of 2023.

For the year ended December 31, 2023, net interest income totaled $156.3 million, an increase of $6.8 million, or 4.5% from the prior year ended December 31, 2022. The Company’s net interest margin for the year ended December 31, 2023 was 3.26% compared to 3.32% in 2022. The increase in net interest income for the year ended December 31, 2023 compared to 2022 reflects an increase in average interest- earning assets that was partially offset by a decrease in the net interest margin.

Non-interest income totaled $9.1 million and $50.7 million, respectively, for the fourth quarter and full year of 2023, compared to $11.5 million and $61.9 million in the respective, comparable year ago periods. These changes were primarily due to variances in mortgage banking related revenues.

Net gains on mortgage loans in the fourth quarters of 2023 and 2022, were approximately $2.0 million and $1.5 million, respectively. For the full year of 2023, net gains on mortgage loans totaled $7.4 million compared to $6.4 million in 2022. The increase in net gains on mortgage loans was due to a combination of higher profit margins on mortgage loan sales and an increase in the volume of mortgage loans sold.

Mortgage loan servicing, net, generated a loss of $2.4 million and a gain of $0.7 million in the fourth quarters of 2023 and 2022, respectively. For the full year of 2023 and 2022, mortgage loan servicing, net, generated income of $4.6 million and $18.8 million, respectively. The significant variances in mortgage loan servicing, net is primarily due to changes in the fair value of capitalized mortgage loan servicing rights attributed to a decrease in interest rates that resulted in a lower earnings rate on escrow deposits and an increase in prepayment speeds. Mortgage loan servicing, net activity is summarized in the following table:


	Three months ended				Twelve months ended
	12/31/2023		12/31/2022		12/31/2023		12/31/2022
	(In thousands)
Mortgage loan servicing, net:

Fair value change due to price	(3,644)		(503)		(280)		14,272
Fair value change due to pay-downs	(1,014)		(990)		(3,922)		(4,076)
Total	$	(2,442)	$	687	$	4,626	$	18,773

Non-interest expenses totaled $31.9 million in the fourth quarter of 2023, compared to $32.1 million in the year-ago period. For the full year of 2023, non-interest expenses totaled $127.1 million versus $128.3 million in 2022.

The Company recorded an income tax expense of $4.2 million and $14.6 million in the fourth quarter and full year of 2023, respectively. This compares to an income tax expense of $3.5 million and $14.4 million in the fourth quarter and full year of 2022, respectively.

Asset Quality

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


	12/31/2023			12/31/2022			12/31/2021
Loan Type	(Dollars in thousands)
Commercial	$	28		$	38		$	62
Mortgage	6,425			4,745			4,914
Installment	970			598			569
Sub total	7,423			5,381			5,545
Less - government guaranteed loans	2,191			1,660			435
Total non-performing loans	$	5,232		$	3,721		$	5,110
Ratio of non-performing loans to total portfolio loans	0.14		%	0.11		%	0.18		%
Ratio of non-performing assets to total assets	0.11		%	0.08		%	0.11		%
Ratio of allowance for credit losses to total non-performing loans	1044.69		%	1409.16		%	924.70		%

The provision for credit losses was credit of $0.6 million and an expense of $1.4 million in the fourth quarters of 2023 and 2022, respectively. The provision for credit losses was an expense of $6.2 million and $5.3 million in the full year of 2023 and 2022, respectively. The quarterly decrease in the provision for credit losses in 2023 compared to 2022, was primarily the result of a change in allocation rates due to subjective factors (prior year allocation rates were increased while current year rates decreased). The Company recorded loan net charge-offs of $0.2 million and $0.1 million in the fourth quarters of 2023 and 2022, respectively. At December 31, 2023, the allowance for credit losses totaled $54.7 million, or 1.44% of total portfolio loans compared to $52.4 million, or 1.51% of total portfolio loans at December 31, 2022.

Balance Sheet, Liquidity and Capital

Total assets were $5.26 billion at December 31, 2023, an increase of $263.9 million from December 31, 2022. Loans, excluding loans held for sale, were $3.79 billion at December 31, 2023, compared to $3.47 billion at December 31, 2022. Deposits totaled $4.62 billion at December 31, 2023, an increase of $243.8 million from December 31, 2022. This increase is primarily due to growth in reciprocal, time and brokered time deposit account balances that were partially offset by decreases in non-interest bearing and savings and interest-bearing checking deposit account balances.

Cash and cash equivalents totaled $169.8 million at December 31, 2023, versus $74.4 million at December 31, 2022. Securities available for sale (“AFS”) totaled $679.4 million at December 31, 2023, versus $779.35 million at December 31, 2022.

Total shareholders’ equity was $404.4 million at December 31, 2023, or 7.68% of total assets compared to $347.6 million or 6.95% at December 31, 2022. Tangible common equity totaled $374.1 million at December 31, 2023, or $17.96 per share compared to $316.7 million or $15.04 per share at December 31, 2022. The increase in shareholder equity as well as tangible common equity are primarily the result of earnings retention and a decline in accumulated other comprehensive loss related to unrealized losses on securities available for sale.

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


Regulatory Capital Ratios	12/31/2023		12/31/2022		Well Capitalized Minimum

Tier 1 capital to average total assets	8.80	%	8.56	%	5.00	%
Tier 1 common equity to risk-weighted assets	11.21	%	10.97	%	6.50	%
Tier 1 capital to risk-weighted assets	11.21	%	10.97	%	8.00	%
Total capital to risk-weighted assets	12.46	%	12.22	%	10.00	%

At December 31, 2023, 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 $1.0 billion and $515.4 million, respectively. We also had approximately $813.8 million in fair value of unpledged securities AFS and HTM at December 31, 2023 which could be pledged for an estimated additional borrowing capacity at the FHLB and FRB of approximately $754.6 million.

Share Repurchase Plan

On December 19, 2023, the Board of Directors of the Company authorized the 2024 share repurchase plan. Under the terms of the 2024 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, 2024. For the full year of 2023, the Company repurchased 298,601 shares at a weighted average price of $17.27 per share.

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, 2022 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

Interest Rate Risk Management • The decrease in the base case modeled NII is due to an adverse shift in the funding mix and the change in rates during the quarter which caused the yield curve to invert further. These changes were partially offset by improvement in asset mix with an increase in loans and a decline in investments and earning asset growth. • The NII sensitivity profile is largely unchanged during the quarter for smaller rate changes of +/- 100 basis points. The exposure to rising rates increased modestly for larger rate increases. asset and liability duration both moved lower but liability duration declined more caused by the adverse shift in the funding mix. • Base-rate is a static balance sheet applying the spot yield curve from the valuation date. • Stable core funding base. Transaction accounts fund 37.8% of assets and other non-maturity deposits fund another 18.8% of assets. Moderate wholesale funding of just 7.9% of assets. • 33.0% of assets reprice in 1 month and 45.9% reprice in the next 12 months. • Continually evaluating strategies to manage NII through hedging as well as product pricing and structure.

Look-Back on 2023 Forecast Outlook for 2023 *as of January, 2023 • IBCP forecast of low double digit (approximately 10%-12%) overall loan growth is based on increases in commercial loans and mortgage loans with installment loans remaining flat. Expect much of this growth to occur in the last three quarters of 2023. • This growth forecast also assumes a stable Michigan economy. • IBCP forecast of high single digit (7%-9%) growth is primarily supported by an increase in earning assets and a favorable shift in the earning asset base. Expect net interest margin (NIM) to be stable to slightly higher (0.05% - 0.10%) in 2023 compared to full-year 2022. • Primary driver is an increase in earning asset yield. The forecast assumes a 0.50% Fed rate increase in February, a 0.25% increase in March and a 0.25% decrease in September and December in the federal funds rate while long-term interest rates decline slightly over year-end 2022 levels. • 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 1.51% at 12/31/22. • A full year 2023. provision (expense) for credit losses of approximately 0.25% to 0.35% of average total portfolio loans would not be unreasonable. 4Q'23 Update • Total portfolio loans increased $49.4 million (5.2% annualized) in 4Q’23 and $325.5 million (9.4%) for the full year 2023 which is slightly lower than our forecasted range. • Commercial and mortgage loans had positive growth for the fourth quarter and full year in 2023. • 4Q'23 net interest income was $0.5 million (4.8% annualized) lower than the prior year quarter. The net interest margin was 3.26% for the current quarter and 3.52 for the prior year quarter and up 0.03% from the linked quarter. • The $0.5 million decrease in net interest income is due to a 0.26% decrease in net interest margin that was partially offset by a $291.2 million increase in average earning assets. Full year 2023 increase of $6.8 million or 4.5%. • The provision for credit losses was a credit of $0.6 million (0.07% annualized). The 4Q'23 provision credit was primarily the result of a change in allocation rates due to subjective factors and the payoff of one problem credit ($1.0 million). Full year 2023 provision expense was $6.2 million or 0.17% of average total loans for the year.

Look-Back on 2023 Forecast Outlook for 2023 *as of January, 2023 • IBCP forecasted 2023 quarterly range of $11M to $13M with the total for the year down 20% to 25% from 2022 actual of $61.9M • Expect mortgage loan origination volumes in 2023 to be down by approximately 20%, a decline in mortgage loan servicing net of approximately 80%, interchange income in 2023 to increase approximately 2.0% to 3.0% as compared to 2022 and service charges on deposits to be collectively comparable to 2022 (a decline in NSF fees to be largely offset by an increase in treasury management related service charges). • IBCP forecasted 2023 quarterly range of $32.0M to $33.5M with the total for the year up 1.5% to 2.5% from the 2022 actual of $128.3M. • The primary driver is an increase in data processing and FDIC deposit insurance premiums. • Approximately an 18.8% effective income tax rate in 2023. This assumes a 21% statutory federal corporate income tax rate during 2023. • 2023 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 2023. 4Q'23 Update • Non-interest income totaled $9.1 million in 4Q'23, which was below the forecasted range. 4Q'23 mortgage loan originations, sales and gains totaled $108.0 million, $86.5 million and $2.0 million, respectively. • Mortgage loan servicing net, generated a loss of $2.4 million in 4Q'23. • Full year 2023 mortgage originations decreased $381.3 million (40.8%). • Full year 2023 quarterly average of $13.4 million which is above our original forecast. • Total non-interest expense was $31.9 million in the 4Q’23, which was below our forecasted range. • The comparative quarterly decrease is primarily due to declines in compensation and employee benefits, occupancy, net, communications expense and loan and collection expense that were partially offset by increases in data processing, FDIC insurance expense, advertising and costs related to unfunded lending commitments. The decrease in compensation and employee benefits is primarily related to a lower expected level of incentive compensation. Full year 2023 quarterly average of $31.8 million. • Actual effective income tax rate of 23.4% and 19.8% for the 4Q’23 and full year, respectively. • 10,200 shares were repurchased in the fourth quarter of 2023 at a average share price of $19.08. 298,601 shares at an average share price of 17.27 have been repurchased for the full year of 2023.

Outlook for 2024 Outlook for 2024 *as of January, 2024 • IBCP forecast of mid-single digit (approximately 6%-8%) overall loan growth is based on increases in commercial loans and mortgage loans with installment loans remaining flat. Expect much of this growth to occur in the first three quarters of 2024. • This growth forecast also assumes a stable Michigan economy. • The forecast assumes 0.25% Fed rate cuts in May, June, August and October in the federal funds rate while long-term interest rates decline slightly over year-end 2023 levels. • IBCP forecast of mid-single digit (6%-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 (0.10% - 0.15%) in 2024 compared to full-year 2023. Primary driver is an increase in earning asset yield that is partially offset by an increase in yield on interest bearing liabilities. • 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 1.44% at 12/31/23 • A full year 2024 provision (expense) for credit losses of approximately 0.15%-0.25% of average total portfolio loans would not be unreasonable.

Outlook for 2024 Outlook for 2024 *as of January, 2024 • IBCP forecasts 2024 quarterly range of $11.5M to $13.0M with the total for the year down 0.5% to 1.0% from 2023 actual of $50.7M • Expect mortgage loan origination volumes in 2024 to increase by approximately 7%, a decline in mortgage loan servicing net of approximately 19%, interchange income in 2024 to increase approximately 1.5% to 2.5% as compared to 2023, service charges on deposits to be collectively comparable to 2023 and other income to decline approximately 5%comparable to 2023 actuals. • IBCP forecasts 2024 quarterly range of $32.5M to $33.5M with the total for the year up 3.5% to 4.25% from the 2023 actual of $127.1M. • The primary driver is an increase in compensation and employee benefits, data processing, loan and collection and advertising. • Approximately a 20% effective income tax rate in 2024 This assumes a 21% statutory federal corporate income tax rate during 2024. • 2024 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.
