INDEPENDENT BANK CORPORATION REPORTS 2024 THIRD QUARTER RESULTS

Third Quarter Highlights

Highlights for the third quarter of 2024 include:

•Increases in net interest income of $0.5 million (or 4.9% annualized) from June 30, 2024;

•An increase in tangible book value per share of $3.69 (22.3%) over the third quarter of 2023;

•Net growth in core deposits of $100.1 million (or 8.9% annualized) from June 30, 2024;

•Net growth in loans of $90.4 million (or 9.3% annualized) from June 30, 2024; and

•The payment of a 24 cent per share dividend on common stock on August 15, 2024.

GRAND RAPIDS, Mich., October 24, 2024 - Independent Bank Corporation (NASDAQ: IBCP) reported third quarter 2024 net income of $13.8 million, or $0.65 per diluted share, versus net income of $17.5 million, or $0.83 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 very pleased with our third quarter 2024 results, driving organic growth on both sides of the balance sheet. Overall loans increased 9.3% (annualized), while core deposits are up 8.9% (annualized). We were able to generate net interest income growth on both a linked quarter basis and on a year over year quarterly basis. We believe that our expenses continue to be well managed, and we continue to see improved operational scale from strategic investments we have made in recent years. Our credit metrics continue to be excellent, with watch credits and non-performing assets near historic lows. These fundamentals continue to drive good growth in tangible book value per share (22%) compared to the prior year quarter. Based on a robust commercial loan pipeline, the past record of our core group of professionals and the on-going strategic initiative to add talented bankers to our team, we are optimistic about continuing these growth trends for the remainder of the year and into 2025.”

Significant items impacting comparable third quarter 2024 and 2023 results include the following:

•Changes in the fair value due to price of capitalized mortgage loan servicing rights (the “MSR Changes”) of  $(4.2) million ($(0.16) per diluted share, after taxes) for the three-month period ended September 30, 2024, as compared to $1.6 million ($0.06 per diluted share, after taxes) for the three-months ended September 30, 2023.

Operating Results

The Company’s net interest income totaled $41.9 million during the third quarter of 2024, an increase of $2.4 million, or 6.2% from the year-ago period, and an increase of $0.5 million, or 1.2%, from the second quarter of 2024. The Company’s tax equivalent net interest income as a percent of average interest-earning assets (the “net interest margin”) was 3.37% during the third quarter of 2024, compared to 3.23% in the year-ago period, and 3.40% in the second quarter of 2024. The year-over-year quarterly increase in net interest income was due to an increase in average interest-earning assets and the net interest margin. The increase in net interest income compared to the linked quarter was due to an increase in average interest earning assets that was partially offset by a decrease in the net interest margin. Average interest-earning assets were $4.99 billion in the third quarter of 2024, compared to $4.89 billion in the year ago quarter and $4.89 billion in the second quarter of 2024.

Non-interest income totaled $9.5 million for the third quarter of 2024, compared to $15.6 million in the comparable prior year period. This change was primarily due to variances in mortgage banking related revenues.

Net gains on mortgage loans in the third quarters of 2024 and 2023, were approximately $2.2 million and $2.1 million, respectively. The comparative quarterly increase in net gains on mortgage loans was primarily due to an increase in both gain on sale margin on mortgage loans sold and a increase in the volume of mortgage loans sold.

Mortgage loan servicing, net, generated income (expense) of $(3.1) million and $2.7 million in the third quarters of 2024 and 2023, 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. Mortgage loan servicing, net activity is summarized in the following table:

	Three months ended				Nine months ended
	9/30/2024		9/30/2023		9/30/2024		9/30/2023
	(In thousands)

Fair value change due to pay-downs	(1,223)		(1,085)		(3,016)		(2,908)
Total	$	(3,130)	$	2,668	$	1,686	$	7,068

Non-interest expenses totaled $32.6 million in the third quarter of 2024, compared to $32.0 million in the year-ago period.

The Company recorded income tax expense of $3.5 million in the third quarterof 2024. This compares to an income tax expense of $4.1 million in the third quarter of 2023. The changes in income tax expense principally reflect changes in pre-tax earnings in 2024 relative to 2023.

Asset Quality

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

	9/30/2024			12/31/2023			9/30/2023
Loan Type	(Dollars in thousands)
Commercial	$	59		$	28		$	31
Mortgage	6,525			6,425			6,137
Installment	666			970			801
Sub total	7,250			7,423			6,969
Less - government guaranteed loans	2,102			2,191			2,254
Total non-performing loans	$	5,148		$	5,232		$	4,715
Ratio of non-performing loans to total portfolio loans	0.13		%	0.14		%	0.13		%
Ratio of non-performing assets to total assets	0.11		%	0.11		%	0.10		%
Ratio of allowance for credit losses to total non-performing loans	1115.85		%	1044.69		%	1176.99		%

The provision for credit losses was an expense of $1.49 million and $1.35 million in the third quarters of 2024 and 2023, respectively. We recorded loan net charge offs (recoveries) of $0.31 million and $(0.18) million in the third quarters of 2024 and 2023, respectively. At September 30, 2024, the allowance for credit losses for loans totaled $57.4 million, or 1.46% of total portfolio loans compared to $54.7 million, or 1.44% of total portfolio loans at December 31, 2023.

Balance Sheet, Capital and Liquidity

Total assets were $5.26 billion at September 30, 2024, a decrease of $4.5 million from December 31, 2023. Loans, excluding loans held for sale, were $3.94 billion at September 30, 2024, compared to $3.79 billion at December 31, 2023.  Deposits totaled $4.63 billion at September 30, 2024, an increase of $4.0 million from December 31, 2023. This increase is primarily due to increases in savings and interest-bearing checking, reciprocal and time deposits that were partially offset by a decrease in non-interest bearings deposits and brokered time deposits.

Cash and cash equivalents totaled $121.6 million at September 30, 2024, versus $169.8 million at December 31, 2023. Securities available for sale (“AFS”) totaled $589.0 million at September 30, 2024, versus $679.4 million at December 31, 2023.

Total shareholders’ equity was $452.4 million at September 30, 2024, or 8.60% of total assets compared to $404.4 million or 7.68% at December 31, 2023. Tangible common equity totaled $422.5 million at September 30, 2024, or $20.22 per share compared to $374.1 million or $17.96 per share at December 31, 2023. The increase in shareholder equity as well as tangible common equity are primarily the result of earnings retention and a decrease in accumulated other comprehensive loss.

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

Regulatory Capital Ratios	9/30/2024		12/31/2023		Well Capitalized Minimum
Tier 1 capital to average total assets	9.36	%	8.80	%	5.00	%
Tier 1 common equity  to risk-weighted assets	11.74	%	11.21	%	6.50	%
Tier 1 capital to risk-weighted assets	11.74	%	11.21	%	8.00	%
Total capital to risk-weighted assets	13.00	%	12.46	%	10.00	%

At September 30, 2024, 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 $1.11 billion and $471.7 million, respectively. We also had approximately $771.3 million in fair value of unpledged securities AFS and HTM at September 30, 2024 which could be pledged for an estimated additional borrowing capacity at the FHLB and FRB of approximately $718.0 million.
